| 1 | S and Pb Isotopic Constraints on the Relationship between the Linong Granodiorite and the Yangla Copper Deposit,Yunnan,China显示文摘The Yangla copper deposit, located in western Yunnan Province, China, is a typical giant, newly started mining copper deposit with an estimated Cu reserves of about 1,200,000 tons. The deposit is spatially and temporally associated with the Linong granodiorite, which is rich in SiO2 (SiO2=58.25 wt%-69.84 wt%) and alkalis (Na2O+K2O=5.98 wt%-8.34 wt%), indicating an association with shoshonitic series to high-K calc-alkaline series granites, and shows low contents of TiO2 (0.35 wt%-0.48 wt%), MgO (1.51 wt%-1.72 wt%), and Al2O3 (13.38 wt%-19.75 wt%). The δ34S values of sulfides of the main ore stage from copper ores vary range from ?4.2‰ to ?0.9‰, indicating a much greater contribution from the mantle to the ore-forming fluids. The δ34S values of the late ore stage is 9.8‰, indicating enrichment of biogenic sulfur which may derive from the crustal hydrothermal fluid. The 208Pb/204Pb, 207Pb/204Pb and 206Pb/204Pb of sulfides of the main ore stage from copper ores range within 38.66-38.73, 15.71-15.74 and 18.35-19.04, respectively, implying that the Pb was derived from the mantle, with the crustal component, probably representing mixtures of mantle lead and crustal lead. Sulfide of the late ore stage in their Pb isotopic composition, 208Pb/204Pb= 38.69, 207Pb/204Pb=15.70, 206Pb/204Pb=18.35, implying that the Pb was derived from the crust. The Linong granodiorite is syn-collisional, produced by partial melting of thickened lower crust, which was triggered by the westward subduction of the Jinshajiang Oceanic plate. During a transition in geodynamic setting from collision-related compression to extension, gently dipping ductile shear zones (related to subduction) were transformed to brittle shear zones, consisting of a series of thrust faults in the Jinshajiang tectonic belt. The tensional thrust faults would have been a favorable environment for ore-forming fluids. The ascending magma provided a channel for the ore-forming fluid from the mantle wedge. After the magma arrived at the base of the early-stage Linong granodiorite, the platy granodiorite at the base of the body would have shielded the late-stage magma from the fluid. The magma would have cooled slowly, and some of the ore-forming fluid in the magma would have entered the gently dipping thrust faults near the Linong granodiorite, resulting in mineralization. | YANG Xi'an LIU Jiajun HAN Siyu WANG Huan CHEN Siyao | 2012 | Acta Geologica Sinica(English Edition)2012，86，6： | 9 |
| 2 | A bottom-up strategy toward metal nano-particles modified graphene nanoplates for fabricating aluminum matrix composites and interface study显示文摘To synthesize graphene economically and efficiently,as well as to improve the interface bonding between graphene and metal and to recede the aggregation issue of graphene,in this work,an easy and scalable bottom-up strategy for the mass production of metal nanoparticles modified graphene nanoplates(GNPs)was proposed.Cu nanoparticles modified GNPs(Cu-GNPs)and Ni nanoparticles modified GNPs(Ni-GNPs)were fabricated through this method,and then compounded with Al via ball milling technique.The asobtained Ni-GNPs/Al composite showed simultaneously improved strength and toughness compared with unreinforced Al,while the Cu-GNPs/Al composite presented a greater strengthening effect.The microstructure and interface of the two composites were carefully characterized and investigated to reveal the difference.First principle study was also adopted to explore the binding energy of different interface structures.This study could provide new insights into the fabrication of GNPs and the control of interface in GNPs/Al composites. | Tielong Han Enzuo Liu Jiajun Li Naiqin Zhao Chunnian He | 2020 | Journal of Materials Science & Technology2020，42，11： | 8 |
| 3 | Thermal Shock-Activated Spontaneous Growing of Nanosheets for Overall Water Splitting显示文摘Nanomaterials based on nickel foam(NF) have been widely applied in energy conversion and storage field.Traditional synthesis methods such as hydrothermal method which is dangerous and high cost limited the scalable developments.Herein,we report a fast,simple,and low-cost synthesis method of nanomaterials based on NF by Joule-heating and water soaking treatment.Thin carbon-coated CoS on NF(NF-C/CoS) was synthesized by Joule-heating for a few seconds with rapid cooling.And then,NF-C/CoS/NiOOH with core-shell heterostructure was fabricated by soaking treatment of NF-C/CoS in water on which NiOOH nanosheets grew spontaneously.The formation mechanism is proposed that the coordination complex precursor converts into C/CoS on NF driven by Joule-heating,and the nickel on the surface of NF is activated to form metastable nickel simultaneously.The metastable nickel reacting with water leads to the formation of NiOOH,and the induction of CoS makes NiOOH grow continuously.This synthesis technology provides a new route to manufacture NF-based nanostructures,and the as-fabricated NF-C/CoS/NiOOH exhibits great potential as electrocatalyst for oxygen evolution reaction and hydrogen evolution reaction. | Han Wu Qi Lu Jinfeng Zhang Jiajun Wang Xiaopeng Han Naiqin Zhao Wenbin Hu Jiajun Li Yanan Chen Yida Deng | 2020 | Nano-Micro Letters2020，12，11： | 6 |
| 4 | Accelerating DNN-based 3D point cloud processing for mobile computing显示文摘3D point cloud data,which are produced by various 3D sensors such as LIDAR and stereo cameras,have been widely deployed by industry leaders such as Google,Uber,Tesla,and Mobileye,for mobile robotic applications such as autonomous driving and humanoid robots.Point cloud data,which are composed of reliable depth information,can provide accurate location and shape characteristics for scene understanding,such as object recognition and semantic segmentation.However,deep neural networks(DNNs),which directly consume point cloud data,are particularly computation-intensive because they have to not only perform multiplication-and-accumulation(MAC)operations but also search neighbors from the irregular 3D point cloud data.Such a task goes beyond the capabilities of general-purpose processors in realtime to figure out the solution as the scales of both point cloud data and DNNs increase from application to application.We present the first accelerator architecture that dynamically configures the hardware onthe-fly to match the computation of both neighbor point search and MAC computation for point-based DNNs.To facilitate the process of neighbor point search and reduce the computation costs,a grid-based algorithm is introduced to search neighbor points from a local region of grids.Evaluation results based on the scene recognition and segmentation tasks show that the proposed design harvests 16.4x higher performance and saves 99.95%of energy than an NVIDIA Tesla K40 GPU baseline in point cloud scene understanding applications. | Bosheng LIU Xiaoming CHEN Yinhe HAN Jiajun LI Haobo XU Xiaowei LI | 2019 | Science China(Information Sciences)2019，62，11： | 4 |
| 5 | Enabling Energy Efficiency in 5G Network显示文摘The mobile Internet and Internet of Things are considered the main driving forc⁃es of 5G,as they require an ultra-dense deployment of small base stations to meet the in⁃creasing traffic demands.5G new radio(NR)access is designed to enable denser network deployments,while leading to a significant concern about the network energy consump⁃tion.Energy consumption is a main part of network operational expense(OPEX),and base stations work as the main energy consumption equipment in the radio access network(RAN).In order to achieve RAN energy efficiency(EE),switching off cells is a strategy to reduce the energy consumption of networks during off-peak conditions.This paper intro⁃duces NR cell switching on/off schemes in 3GPP to achieve energy efficiency in 5G RAN,including intra-system energy saving(ES)scheme and inter-system ES scheme.Addition⁃ally,NR architectural features including central unit/distributed unit(CU/DU)split and dual connectivity(DC)are also considered in NR energy saving.How to apply artificial in⁃telligence(AI)into 5G networks is a new topic in 3GPP,and we also propose a machine learning(ML)based scheme to save energy by switching off the cell selected relying on the load prediction.According to the experiment results in the real wireless environment,the ML based ES scheme can reduce more power consumption than the conventional ES scheme without load prediction. | LIU Zhuang GAO Yin LI Dapeng CHEN Jiajun HAN Jiren | 2021 | ZTE Communications2021，19，1： | 4 |
| 6 | Routing valley exciton emission of a WS_(2) monolayer via delocalized Bloch modes of in-plane inversion-symmetry-broken photonic crystal slabs显示文摘The valleys of two-dimensional transition metal dichalcogenides(TMDCs)offer a new degree of freedom for information processing.To take advantage of this valley degree of freedom,on the one hand,it is feasible to control valleys by utilizing different external stimuli,such as optical and electric fields.On the other hand,nanostructures are also used to separate the valleys by near-field coupling.However,for both of the above methods,either the required low-temperature environment or low degree of coherence properties limit their further applications.Here,we demonstrate that all-dielectric photonic crystal(PhC)slabs without in-plane inversion symmetry(C_(2) symmetry)can separate and route valley exciton emission of a WS2 monolayer at room temperature.Coupling with circularly polarized photonic Bloch modes of such PhC slabs,valley photons emitted by a WS_(2) monolayer are routed directionally and are efficiently separated in the far field.In addition,far-field emissions are directionally enhanced and have long-distance spatial coherence properties. | Jiajun Wang Han Li Yating Ma Maoxiong Zhao Wenzhe Liu Bo Wang Shiwei Wu Xiaohan Liu Lei Shi Tian Jiang Jian Zi | 2020 | Light(Science & Applications)2020，9，1： | 4 |
| 7 | Fabrication of Graphene Nanoplates Modified with Nickel Nanoparticles for Reinforcing Copper Matrix Composites显示文摘In order to improve the interface wettability as well as the interfacial bonding between graphene and copper matrix,in this work,graphene nanoplates modified with nickel nanoparticles(Ni-GNPs)were synthesized using a one-step method based on spray-drying and chemical vapor deposition.Thereafter,0.33 wt%Ni-GNPs were introduced into copper matrix composite by the molecular-level mixing method,leading to further enhancement of 90%in yield strength.This is attributed to the presence of Ni-GNPs,which provided high resistance to matrix against deformation.In addition,with the modification of nickel at the interface,the wettability and interfacial bonding between graphene nanoplates and copper matrix were improved,which enhanced the load transfer then.Furthermore,the microstructures and strengthening mechanisms were investigated and discus sed meanwhile. | Tielong Han Jiajun Li Naiqin Zhao Chunnian He | 2020 | Acta Metallurgica Sinica(English Letters)2020，33，5： | 3 |
| 8 | Intense single-band red upconversion emission in BiOCl:Er3+ layered semiconductor via co-doping Ho3+显示文摘Exploring a new tuning way to facilely realize single-band red emission in trivalent rare-earth ions(RE3+) doped upconversion(UC) materials is still desirable.In this work,the intense single-band red emission is achieved by co-doping only Ho3+in the BiOCl:Er3+ under 1550 nm excitation.In the BiOCl layered host,co-doping Ho3+can further enhance the red emission and simultaneously suppress the green emission of Er3+,and thus obviously improve the red-to-green(R/G) ratio.It is found that Ho3+does not se rve as ene rgy trapping through the 5 I6 state as in traditional UC materials but acts as ET bridge(4 S3/2,2 H11/2(Er3+)→5 F4,5 S2(Ho3+)→4 F9/2(Er3+)).The tuning mechanism of Ho3+is discussed in detail and further confirms through a comparative experiment.Our research gives an unusual perspective to tune the UC behavior of Er3+through co-doping Ho3+,which might be inspiring for achievement of single-band red UC emission. | Yuehong Peng Jincai Peng Jiajun Han Tianhui Wang Zhaoyi Yin Jianbei Qiu Qi W ang Zhengwen Yang Zhiguo Song | 2020 | Journal of Rare Earths2020，38，6： | 2 |
| 9 | Connections between Evaporite Deposition and Glacial Periods since the Middle Pleistocene in Salt Lakes in the Western Qaidam Basin, China显示文摘The Quaternary was the main evaporite deposition period in the Qaidam Basin(QB), but the correlation between the evaporite deposition period and the glacial period is still unclear. In this study, the research objects are primarily evaporite-bearing strata in a 461.58 m-long drill core in the QB. X-ray powder diffraction(XRD) and scanning electron microscopy(SEM) were applied to study the evaporite minerals, U-Th dating being applied to construct the ~(230)Th geochronological framework. Evaporite deposition from Marine Isotope Stage(MIS) 15 to MIS 4 in the borehole was reconstructed via mineralogical and geochronological data. The evaporite minerals are mainly halite(NaCl), mirabilite(Na_(2)SO_(4)·10H_(2)O), thenardite(Na_(2)SO_(4)) and gypsum(CaSO_(4)·2H_(2)O). A total of 9 effective ~(230)Th data points, ranging from 492.5 ± 43.0 ka to 62.0 ± 11.9 ka, were obtained. The depositional age of the earliest halite layer in the borehole is 592.5–563.0 ka. There were mirabilite deposits in the QB during the cold glacial environment of MIS 6. During MIS 4, the study area desiccated, with mirabilite and halite being deposited. This study suggests that mirabilite is an indicator mineral for the glacial environment in the QB, while halite deposition does not correspond well to glaciation. | GU Jiani CHEN Andong LIU Jiajun HAN Guang WANG Xuefeng | 2022 | Acta Geologica Sinica(English Edition)2022，96，5： | 2 |
| 10 | Stem cell transplantation for treating stroke:status,trends and development显示文摘The developing approaches of thrombolytic therapy, endovascular treatment, neuroprotective therapy, and stem cell therapy have enabled breakthroughs in stroke treatment. In this study, we summarize and analyze trends and progress in stem cell transplantation for stroke treatment by retrieval of literature from Thomson Reuters Web of Science database, the NIH Clinical Trial Planning Grant Program, and Clinical Trials Registration Center in North America. In the last 10 years, there has been an increasing number of published articles on stem cell transplantation for stroke treatment. In particular, research from the USA and China has focused on stem cell transplantation. A total of 2,167 articles addressing stem cell transplantation for stroke treatment from 2004 to 2013 were retrieved from the Thomson Reuters Web of Science database. The majority of these articles were from the USA(854, 39.4%), with the journal Stroke publishing the most articles(145, 6.7%). Of the published articles, 143 were funded by the National Institutes of Health(accounting for 6.6% of total publications), and 91 by the National Natural Science Foundation of China. Between 2013 and 2014, the National Institutes of Health provided financial support($130 million subsidy) for 329 research projects on stroke therapy using stem cell transplantation. In 2014, 215 new projects were approved, receiving grants of up to $70,440,000. Ninety clinical trials focusing on stem cell transplantation for stroke were registered in the Clinical Trial Registration Center in North America, with 40 trials registered in the USA(ranked first place). China had the maximum number of registered research or clinical trials(10 projects). | Wenxin Huo Xiaoyang Liu Cheng Tan Yingying Han Chunyang Kang Wei Quan Jiajun Chen | 2014 | Neural Regeneration Research2014，9，17： | 2 |
| 11 | Understanding and addressing the environmental risk of microplastics显示文摘Over the past decades,the plastic production has been dramatically increased.Indeed,a category of small plastic particles mainly with the shapes of fragments,fibers,or spheres,called microplastics(particles smaller than 5 mm)and nanoplastics(particles smaller than 1μm)have attracted particular attention.Because of its wide distribution in the environment and potential adverse effects to animal and human,microplastic pollution has been reported as a serious environment problem receiving increased attention in recent years.As one of the commonly detected emerging contaminants in the environment,recent evidence indicates that the concentration of microplastics show an increasing trend,for the reason that up to 12.7 million metric tons of plastic litter is released into aquatic environment from land-based sources each year.Furthermore,microplastic exposure levels of model organisms in laboratory studies are usually several orders of magnitude higher than those found in environment,and the microplastics exposure conditions are also different with those observed in the environment.Additionally,the detection of microplastics in feces indicates that they can be excreted out of the bodies of animal and human.Hence,great uncertainties might exist in microplastics exposure and health risk assessment based on current studies,which might be exaggerated.Policies reduce microplastic emission sources and hence minimize their environmental risks are determined.To promote the above policies,we must first overcome the technical obstacles of detecting microplastics in various samples. | Han Qu Hongting Diao Jiajun Han Bin Wang Gang Yu | 2023 | Frontiers of Environmental Science & Engineering2023，17，1： | 1 |
| 12 | Single-event burnout hardening of planar power MOSFET with partially widened trench source显示文摘We present a single-event burnout(SEB) hardened planar power MOSFET with partially widened trench sources by three-dimensional(3 D) numerical simulation. The advantage of the proposed structure is that the work of the parasitic bipolar transistor inherited in the power MOSFET is suppressed effectively due to the elimination of the most sensitive region(P-well region below the N+ source). The simulation result shows that the proposed structure can enhance the SEB survivability significantly. The critical value of linear energy transfer(LET),which indicates the maximum deposited energy on the device without SEB behavior, increases from 0.06 to0.7 p C/μm. The SEB threshold voltage increases to 120 V, which is 80% of the rated breakdown voltage. Meanwhile, the main parameter characteristics of the proposed structure remain similar with those of the conventional planar structure. Therefore, this structure offers a potential optimization path to planar power MOSFET with high SEB survivability for space and atmospheric applications. | Jiang Lu Hainan Liu Xiaowu Cai Jiajun Luo Bo Li Binhong Li Lixin Wang Zhengsheng Han | 2018 | Journal of Semiconductors2018，39，3： | 1 |

| 14 | Cross-Target Transfer Algorithm Based on the Volterra Model of SSVEP-BCI显示文摘In general, a large amount of training data can effectively improve the classification performance of the Steady-State Visually Evoked Potential(SSVEP)-based Brain-Computer Interface(BCI) system. However, it will prolong the training time and considerably restrict the practicality of the system. This study proposed a SSVEP nonlinear signal model based on the Volterra filter, which could reconstruct stable reference signals using relatively small number of training targets by transfer learning, thereby reducing the training cost of SSVEP-BCI. Moreover,this study designed a transfer-extended Canonical Correlation Analysis(t-eCCA) method based on the model to achieve cross-target transfer. As a result, in a single-target SSVEP experiment with 16 stimulus frequencies,t-eCCA obtained an average accuracy of 86.96%˙12.87% across 12 subjects using only half of the calibration time,which exhibited no significant difference from the representative training classification algorithms, namely, extended canonical correlation analysis(88.32%±13.97%) and task-related component analysis(88.92%±14.44%), and was significantly higher than that of the classic non-training algorithms, namely, Canonical Correlation Analysis(CCA) as well as filter-bank CCA. Results showed that the proposed cross-target transfer algorithm t-eCCA could fully utilize the information about the targets and its stimulus frequencies and effectively reduce the training time of SSVEP-BCI. | Jiajun Lin Liyan Liang Xu Han Chen Yang Xiaogang Chen Xiaorong Gao | 2021 | Tsinghua Science and Technology2021，26，4： | 1 |
| 15 | Crosslinking and functionalization of acellular patches via the self-assembly of copper@tea polyphenol nanoparticles显示文摘Decellularization is a promising technique to produce natural scaffolds for tissue engineering applications.However,non-crosslinked natural scaffolds disfavor application in cardiovascular surgery due to poor biomechanics and rapid degradation.Herein,we proposed a green strategy to crosslink and functionalize acellular scaffolds via the self-assembly of copper@tea polyphenol nanoparticles(Cu@TP NPs),and the resultant nanocomposite acellular scaffolds were named as Cu@TP-dBPs.The crosslinking degree,biomechanics,denaturation temperature and resistance to enzymatic degradation of Cu@TP-dBPs were comparable to those of glutaraldehyde crosslinked decellularized bovine pericardias(Glut-dBPs).Furthermore,Cu@TP-dBPs were biocompatible and had abilities to inhibit bacterial growth and promote the formation of capillary-like networks.Subcutaneous implantation models demonstrated that Cu@TP-dBPs were free of calcification and allowed for host cell infiltration at Day 21.Cardiac patch graft models confirmed that Cu@TP-dBP patches showed improved ingrowth of functional blood vessels and remodeling of extracellular matrix at Day 60.These results suggested that Cu@TP-dBPs not only had comparable biomechanics and biostability to Glut-dBPs,but also had several advantages over Glut-dBPs in terms of anticalcification,remodeling and integration capabilities.Particularly,they were functional patches possessing antibacterial and proangiogenic activities.Thesematerial properties and biological functionsmade Cu@TP-dBPs a promising functional acellular patch for cardiovascular applications. | Qin Li Yuan Gao Jiajun Zhang Yangfeng Tang Yangyong Sun Lujia Wu Hao Wu Meifang Shen Xiaohong Liu Lin Han Zhiyun Xu | 2022 | Regenerative Biomaterials2022，9，1： | 1 |

| 18 | Electron-ion collider in China显示文摘Lepton scattering is an established ideal tool for studying inner structure of small particles such as nucleons as well as nuclei.As a future high energy nuclear physics project,an Electron-ion collider in China(EicC)has been proposed.It will be constructed based on an upgraded heavy-ion accelerator,High Intensity heavy-ion Accelerator Facility(HIAF)which is currently under construction,together with a new electron ring.The proposed collider will provide highly polarized electrons(with a po-larization of 80%)and protons(with a polarization of 70%)with variable center of mass energies from 15 to 20 GeV and the luminosity of(2–3)×1033 cm^(−2)·s^(−1).Polarized deuterons and Helium-3,as well as unpolarized ion beams from Carbon to Uranium,will be also available at the EicC.The main foci of the EicC will be precision measurements of the structure of the nucleon in the sea quark region,including 3D tomography of nucleon;the partonic structure of nuclei and the parton interaction with the nuclear environment;the exotic states,especially those with heavy flavor quark contents.In addition,issues fundamental to understanding the origin of mass could be addressed by measurements of heavy quarkonia near-threshold production at the EicC.In order to achieve the above-mentioned physics goals,a hermetical detector system will be constructed with cutting-edge technologies.This document is the result of collective contributions and valuable inputs from experts across the globe.The EicC physics program complements the ongoing scientific programs at the Jefferson Laboratory and the future EIC project in the United States.The success of this project will also advance both nuclear and particle physics as well as accelerator and detector technology in China. | Daniele PAnderle Valerio Bertone Xu Cao Lei Chang Ningbo Chang Gu Chen Xurong Chen Zhuojun Chen Zhufang Cui Lingyun Dai Weitian Deng Minghui Ding Xu Feng Chang Gong Longcheng Gui Feng-Kun Guo Chengdong Han Jun He Tie-Jiun Hou Hongxia Huang Yin Huang KrešImir KumeričKi LPKaptari Demin Li Hengne Li Minxiang Li Xueqian Li Yutie Liang Zuotang Liang Chen Liu Chuan Liu Guoming Liu Jie Liu Liuming Liu Xiang Liu Tianbo Liu Xiaofeng Luo Zhun Lyu Boqiang Ma Fu Ma Jianping Ma Yugang Ma Lijun Mao Cédric Mezrag HervéMoutarde Jialun Ping Sixue Qin Hang Ren Craig DRoberts Juan Rojo Guodong Shen Chao Shi Qintao Song Hao Sun PawełSznajder Enke Wang Fan Wang Qian Wang Rong Wang Ruiru Wang Taofeng Wang Wei Wang Xiaoyu Wang Xiaoyun Wang Jiajun Wu Xinggang Wu Lei Xia Bowen Xiao Guoqing Xiao Ju-Jun Xie Yaping Xie Hongxi Xing Hushan Xu Nu Xu Shusheng Xu Mengshi Yan Wenbiao Yan Wencheng Yan Xinhu Yan Jiancheng Yang Yi-Bo Yang Zhi Yang Deliang Yao Zhihong Ye Peilin Yin C-PYuan Wenlong Zhan Jianhui Zhang Jinlong Zhang Pengming Zhang Yifei Zhang Chao-Hsi Chang Zhenyu Zhang Hongwei Zhao Kuang-Ta Chao Qiang Zhao Yuxiang Zhao Zhengguo Zhao Liang Zheng Jian Zhou Xiang Zhou Xiaorong Zhou Bingsong Zou Liping Zou | 2021 | Frontiers of physics2021，16，6： | 1 |

| 20 | A bifunctional perovskite oxide catalyst:The triggered oxygen reduction/evolution electrocatalysis by moderated Mn-Ni co-doping显示文摘ABO_(3)-type perovskite oxides(e.g.,LaCoO_(3))with flexible and adjustable A-and B-sites are ideal model catalysts to unravel the relationship between the electronic structure and electrocatalytic activity(e.g.,oxygen reduction/evolution reactions,ORR/OER).It has been well understood in our recent work that the secondary metal dopant at B-site(e.g.,Mn in LaMn_(x)Co_(1-x)O_(3))can regulate the electronic structure and improve the ORR/OER activity.In this work,the Mn-Ni pairs are employed as the dual dopant in LaMn_(x)Ni_(y)Co_(z)O_(3)(x+y+z=1)catalysts toward bifunctional ORR and OER.The structure-property relationships between the triple metal B-site(Mn,Ni and Co)and the electrochemical performance are particularly investigated.Compared to the individual Mn doping(e.g.,LaMnCoO3(Mn:Co=1:3)catalyst),the dual Mn-Ni doping significantly improves the ORR mass activity@0.8 V by 1.54 times;meanwhile,the OER overpotential@10 mA cm^(-2) is reduced from 420 to 370 mV,and the OER current density at 1.55 V is increased by 2.43 times.Reasonably,the potential gap between EDRR@-1 mA cm^(-2) and EDER@10 mA cm^(-2) is achieved as only 0.76 V by using the optimal LaMn_(x)Ni_(y)Co_(z)O_(3)(x:y:z=1:2:3)catalyst.It is revealed that the dual Mn-Ni dopant efficiently optimizes electron structures of the LaMnNiCoO_(3)(1:2:3)catalyst,which not only decreases the e_(g) orbital electron number,but also modulates the O 2 p-band closer to the Femi level,accounting for the enhanced bifunctional activity. | Jia Sun Lei Du Baoyu Sun Guokang Han Yulin Ma Jiajun Wang Hua Huo Pengjian Zuo Chunyu Du Geping Yin | 2021 | Journal of Energy Chemistry2021，30，3： | 1 |
