| 3 | Metal-organic framework-derived Fe/Cu-substituted Co nanoparticles embedded in CNTs-grafted carbon polyhedron for Zn-air batteries显示文摘Metal-organic frameworks(MOFs)and MOF-derived materials have attracted great attention as alternatives to noble-metal based electrocatalysts owing to their intriguing structure properties,especially for high efficiency and stable oxygen reduction reaction(ORR).Herein,we employed a one-pot reaction to make a multimetal(Fe,Co,Cu,and Zn)mixed zeolitic imidazolate framework(MM-ZIF)via adopting a simple in situ redox reaction.Further pyrolysis of the target MM-ZIF,a highly porous carbon polyhedron(FC-C@NC)grafted with abundant carbon nanotubes was obtained,in which ultrasmall Co nanoparticles with partial lattice sites substituted by Fe and Cu were embedded.The obtained FC-C@NC possessed large surface area,highly porous structure,widely-spread metal active sites,and conductive carbon frameworks,contributing to outstanding ORR activity and long-term stability.It displayed superior tolerance to methanol crossover and exceeded the commercial Pt/C catalyst and most previously reported non-noble-metal catalysts.Impressively,the as-produced FC-C@NC-based zinc-air battery afforded an open-circuit potential of 1.466 V,a large specific capacity of 659.5 mAh/g,and a high gravimetric energy density of 784.3 Wh/kgZn,significantly outperforming the Pt/C-based cathode. | Kexin Zhang Yelong Zhang Qinghua Zhang Zibin Liang Lin Gu Wenhan Guo Bingjun Zhu Shaojun Guo Ruqiang Zou | 2020 | Carbon Energy2020，2，2： | 7 |
| 4 | Co-doped IT-M0S2 nanosheets embedded in N,S-doped carbon nanobowls for high-rate and ultra-stable sodium-ion batteries显示文摘Despite various 2H-MoS/carbon hybrid nanostructures have been constructed and committed to improve the performance for sodium-ion batteries(SIBs),they still show the limited cycle stability due to the relatively large volumetric expansion during the charge-discharge process Herein,we report the construction of cobalt-doped few-layered 1T-MoS2 nanosheets embedded in N,S-doped carbon(CMS/NSC)nanobowls derived from metal-organic framework(MOF)precursor via a simple in situ sulfurization process.This unique hierarchical structure enables the uniformly dispersed Co-doped 1T-MoS2 nanosheets intimately couple with the highly conductive carbon nanobowls,thus efficiently preventing the aggregation.In particular,the Co-doping plays a crucial role in maintaining the integrity of structure for MoS2 during cycling tests,confirmed by first-principles calculations.Compared with pristine MoS2,the volume deformation of Co-doped MoS2 can be shrunk by a prominent value of 52%during cycling.Furthermore,the few-layered MoS2 nanosheets with 1T metalic phase endow higher conductivity,and thus can surpass its counterpart 2H semiconducting phase in battery performance.By virtue of the synergistic effect of stable structure,appropriate doping and high conductivity,the resulting CMS/NSC hybrid shows superior rate capability and cycle stability.The capacity of CMS/NSC can still be 235.9 mAh·g^-1 even at 25 A·g^-1,which is 51.3%of the capacity at 0.2 A·g^-1.Moreover,the capacity can still remain 218.6 mAh·g^-1 even over 8,240 cycles at 5 Ag·g^-1 with a low decay of 0.0044%per cycle,one of the best performances among the reportec MoS2-based anode materials for SIBs. | Peihao Li Yong Yang Sheng Gong Fan Lv Wei Wang Yiju Li Mingchuan Luo Yi Xing Qian Wang Shaojun Guo | 2019 | Nano Research2019，12，9： | 6 |
| 5 | Recent progress on precious metal single atom materials for water splitting catalysis显示文摘Electrochemical water splitting for hydrogen production has sparked intensive interests because it provides a new approach for sustainable energy resources and the avoidance of environmental problems.The precious metal-based sin-gle atomic catalysts(PMSACs)have been widely employed in water splitting catalysis by virtue of their maximum atom utilization and unique electronic structure,which can reduce metal amounts and remain high catalytic perfor-mance simultaneously.In this review,we will summarize recent research efforts toward developing SACs based on precious metals with excellent performance for electrochemical water splitting catalysis.First,the synthesis strategies for PMSACs will be classified and introduced including high-temperature pyrolysis,electrochemical method,photochemical reduction,wet chemistry method,etc.Then,a short description of characterization techniques for SACs will be given,which mainly involves the aberration-corrected scanning-transmission electron microscopy(AC-STEM)and X-ray absorption spectroscopy(XAS).In particular,the relationship between the electronic structure of the precious metal atomic sites and performance for water splitting will be discussed according to the the-oretical and experimental results.Finally,a brief perspective will be provided to highlight the challenges and opportunities for the development of novel PMSACs suitable for electrochemical water splitting applications. | Lei Zhou Shi-Yu Lu Shaojun Guo | 2021 | SusMat2021，1，2： | 6 |
| 6 | In-situ observations of damage-fracture evolution in surrounding rock upon unloading in 2400-m-deep tunnels显示文摘The damage-fracture evolution of deep rock mass has obvious particularity,which is revealed in 2400-mdeep tunnels by field tests.The evolution of the excavation damaged zone depth is consistent with that of the fractured zone depth.The ratio of the excavation damaged zone depth to the excavation fractured zone depth is greater than 2.0 in a rock mass with both high strength and good integrity,but less than1.5 in a rock mass with lower strength or poor integrity.Zonal disintegration in a rock mass with high strength and fair integrity is more likely to occur when it contains more than two groups of primary fractures in damaged zones.Fractures develop outward in zonal disintegration but are totally different from the single-zone fracture,in which the fractures develop inward,and it is the starting position of the fractured zone when the excavation surface of the middle pilot is 7–9 m close to the pre-set borehole and it stops after the excavation surface of the baseplate is 11–14 m away.The most intense evolution occurs around 2–4 m from the pre-set borehole in the sidewall expansion stage.The research results provide a reference for the monitoring scheme and support design of CJPL-Ⅲin its future construction. | Haosen Guo Qiancheng Sun Guangliang Feng Shaojun Li Yaxun Xiao | 2023 | International Journal of Mining Science and Technology2023，33，4： | 5 |
| 7 | Rh-doped PdAg nanoparticles as efficient methanol tolerance electrocatalytic materials for oxygen reduction显示文摘Direct methanol fuel cells(DMFCs)have received extensive attention on their high efficiency,high reliability,and no carbon emission.Unfortunately,the poor methanol tolerance and sluggish oxygen reduction reaction(ORR)at cathode have seriously hindered their further development.Herein we report the synthesis of a new class of Rh-doped PdAg alloy nanoparticles(NPs)for boosting ORR activity with high methanol tolerance capacity concurrently.The ORR mass activity of typical Rh_4Pd_(40)Ag_(56)NPs is 4.2 times higher than that of commercial Pt catalyst.Moreover,it shows a great methanol tolerance capability by maintaining 92.4%in ORR mass activity in alkaline solution with 0.1 mol L^(à1)methanol,against a big decrease of almost 100%for commercial Pt.Even after 30,000 potential cycles with 1.0 mol L^(à1)methanol,Rh_4Pd_(40)Ag_(56)NPs still retain ORR mass activity of up to 68.3%.DFT calculations reveal that excellent ORR performance with excellent methanol tolerance originates the active d-band-pinning engineering for an efficient site-independent electron-transfer.A generalized d-band mediated fine electron-transfer tuning path has blueprinted for effectively minimizing intrinsic ORR barriers with high current density.The present work highlights the key role of Rh doping in enhancing the ORR activity and methanol tolerance ability of PdAg NPs for future high-performance DMFCs. | Yingjun Sun Bolong Huang Nuoyan Xu Yingjie Li Mingchuan Luo Chunji Li Yingnan Qin Lei Wang Shaojun Guo | 2019 | Science Bulletin2019，64，1： | 4 |
| 8 | 3D star-like atypical hybrid MOF derived single-atom catalyst boosts oxygen reduction catalysis显示文摘Developing high-efficiency,stable and non-precious electrocatalysts for oxygen reduction reaction(ORR)is highly important for energy conversion and storage.Single atom catalysts(SACs)show good potential in enhancing ORR,however,the specifical control over the coordination surroundings around single metal center to intrinsically modify the electron structure is still a great challenge.Herein,we demonstrate that a 3 D hybrid MOF composed of cobalt doped ZIF-L and ZIF-8,featuring star morphology with six equal branches,can be used as an advanced precursor for making the Co SACs for greatly boosted ORR.The as-synthesized Co_(SA)-N-C exhibits excellent ORR activity with E_(1/2) of 0.891 V in alkaline medium,outperforming the commercial Pt/C by 39 m V.Moreover,the E_(1/2) of Co_(SA)-N-C(0.790 V)is merely 15 m V,less than that of Pt/C(0.805 V)in acid medium,which is among the best in the reported state-of-the-art SACs.DFT calculations demonstrate that the enhanced ORR performance is assigned to the formation of atomically isolated cobalt atom coordinated three N atoms and one C atom,which is easier to decrease the free energy of rate determining step and accelerate the ORR process than that of traditional cobalt atom coordinated four N atoms.In addition,a primary Zn-air battery with Co_(SA)-N-C cathode reveals a maximum power density of 92.2 m W cm^(-2) at 120.0 m A cm^(-2),far higher than that of commercial catalysts(74.2 m W cm^(-2) at 110.0 m A cm^(-2)). | Lei Zhou Peng Zhou Yelong Zhang Bingyao Liu Peng Gao Shaojun Guo | 2021 | Journal of Energy Chemistry2021，30，4： | 4 |
| 9 | Wet spinning of fiber-shaped flexible Zn-ion batteries toward wearable energy storage显示文摘High-performance flexible one-dimensional(1D)electrochemical energy storage devices are crucial for the applications of wearable electronics.Although much progress on various 1D energy storage devices has been made,challenges involving fabrication cost,scalability,and efficiency remain.Herein,a highperformance flexible all-fiber zinc-ion battery(ZIB)is fabricated using a low-cost,scalable,and efficient continuous wet-spinning method.Viscous composite inks containing cellulose nanofibers/carbon nanotubes(CNFs/CNTs)binary composite network and either manganese dioxide nanowires(MnO_(2) NWs)or commercial Zn powders are utilized to spinning fiber cathodes and anodes,respectively.MnO_(2) NWs and Zn powders are uniformly dispersed in the interpenetrated CNFs/CNTs fibrous network,leading to homogenous composite inks with an ideal shear-thinning property.The obtained fiber electrodes demonstrate favorable uniformity and flexibility.Benefiting from the well-designed electrodes,the assembled flexible fiber-shaped ZIB delivers a high specific capacity of 281.5 m Ah g^(-1) at 0.25 A g^(-1) and displays excellent cycling stability over 400 cycles.Moreover,the wet-spun fiber-shaped ZIBs achieve ultrahigh gravimetric and volumetric energy densities of 47.3 Wh kg^(-1) and 131.3 m Wh cm^(-3),respectively,based on both cathode and anode and maintain favorable stability even after 4000 bending cycles.This work offers a new concept design of 1D flexible ZIBs that can be potentially incorporated into commercial textiles for wearable and portable electronics. | Tingting Gao Guangyuan Yan Xin Yang Qing Yan Yankuan Tian Jianwei Song Faxue Li Xueli Wang Jianyong Yu Yiju Li Shaojun Guo | 2022 | Journal of Energy Chemistry2022，31，8： | 3 |
| 10 | HSPOG:An Optimized Target Recognition Method Based on Histogram of Spatial Pyramid Oriented Gradients显示文摘The Histograms of Oriented Gradients(HOG)can produce good results in an image target recognition mission,but it requires the same size of the target images for classification of inputs.In response to this shortcoming,this paper performs spatial pyramid segmentation on target images of any size,gets the pixel size of each image block dynamically,and further calculates and normalizes the gradient of the oriented feature of each block region in each image layer.The new feature is called the Histogram of Spatial Pyramid Oriented Gradients(HSPOG).This approach can obtain stable vectors for images of any size,and increase the target detection rate in the image recognition process significantly.Finally,the article verifies the algorithm using VOC2012 image data and compares the effect of HOG. | Shaojun Guo Feng Liu Xiaohu Yuan Chunrong Zou Li Chen Tongsheng Shen | 2021 | Tsinghua Science and Technology2021，26，4： | 3 |
| 11 | Single-atom catalysts supported on ordered porous materials:Synthetic strategies and applications显示文摘Single-atom catalysts(SACs)are attracting extensive attention due to their incredibly catalytic activity and selectivity,high utilization of metal atoms,and obvious cost reduction.The unique ordered porous materials(OPMs)are promising carriers for stabilizing single atoms due to their large surface areas and uniformly tunable pore sizes.Meantime,the geometric and electronic structures of single-atom metals can be tuned by the interaction between the single-atoms(SAs)and OPMs to enhance the catalytic activity of SACs.The SACs based on OPMs,such as zeolites,metal-organic frameworks,and ordered mesoporous materials,have been developing fast recently.Herein,we review recent advancements on structural feature,synthetic strategy,characterization technique,and catalytic applications of OPMs-based SACs.The opportunities and challenges about SAs/OPMs are also provided to develop the novel catalysts with superior catalytic performances in the future. | Kaiwen Xue Yan Mo Baojun Long Wen Wei Changsheng Shan Shaojun Guo Li Niu | 2022 | InfoMat2022，4，6： | 3 |
| 12 | Online recognition of the multiphase flow regime显示文摘The key reasons that the present method cannot be used to solve the industrial multi- phase flow pattern recognition are clarified firstly. The prerequisite to realize the online recognition is proposed and recognition rules for partial flow pattern are obtained based on the massive experimental data. The standard templates for every flow regime feature are calculated with self-organization cluster algorithm. The multi-sensor data fusion method is proposed to realize the online recognition of multiphase flow regime with the pressure and differential pressure signals, which overcomes the severe influence of fluid flow velocity and the oil fraction on the recognition. The online recognition method is tested in the practice, which has less than 10 percent measurement error. The method takes advantages of high confidence, good fault tolerance and less requirement of single sensor performance. | BAI BoFeng ZHANG ShaoJun ZHAO Liang ZHANG XiMin GUO LieJin | 2008 | Science China(Technological Sciences)2008，51，8： | 2 |
| 13 | Near Infrared Star Centroid Detection by Area Analysis of Multi-Scale Super Pixel Saliency Fusion Map显示文摘The centroid location of a near infrared star always deviates from the real center due to the effects of surrounding radiation. To determine a more accurate center of a near infrared star, this paper proposes a method to detect the star's saliency area and calculate the star's centroid via the pixels only in this area, which can greatly decrease the effect of the radiation. During saliency area detection, we calculated the boundary connectivity and gray similarity of every pixel to estimate how likely it was to be a background pixel. Aiming to simplify and speed up the calculation process, we divided the near infrared starry sky image into super pixel maps at multi-scale by Simple Linear Iterative Clustering(SLIC). Second, we detected the saliency map for every super pixel map of the image. Finally, we fused the saliency maps according to a weighted coefficient that is determined by the least square method. For the images used in our experiment, we set the multi-scale super pixel numbers to 100, 150,and 200. The results show that our method can obtain an offset variance of less than 0.27 for the center coordinates compared to the labelled centers. | Xiaohu Yuan Shaojun Guo Chunwen Li Bin Lu Shuli Lou | 2019 | Tsinghua Science and Technology2019，24，3： | 2 |
