| 4 | Space-confined growth of monolayer ReSe2 under a graphene layer on Au foils显示文摘Vertical heterostructures based on two-dimensional(2D)materials have attracted widespread interest for their numerous applications in electronic and optoelectronic devices.Herein,we report the direct construct!on of an abnormal graphene/ReSe2 stack on Au foils by a two-step chemical vapor deposition(CVD)strategy.During the second growth stage,mono layer ReSe2 is found to prefere ntially evolve at the irUerface between the first-grown graphene layer and the Au substrate.The unusual stacking behavior is unraveled by in-situ'cutting open'the upper graphene from the defects to expose the lower ReSe2 using scanning tunneling microscopy(STM).From combination of these results with density functional theory calculations,the domain boundaries and edge sites of graphene are proposed to be adsorption sites for Re and Se precursors,further facilitating the growth of ReSe2 at the van der Waals gap of graphene/Au.This work hereby offers an intriguing strategy for obtaining vertical 2D heterostructures featured with an ultra-clean interface and a designed stacking geometry. | Chunyu Xie Shaolong Jiang Xiaolong Zou Yuanwei Sun Liyun Zhao Min Hong Shulin Chen Yahuan Huan Jianping Shi Xiebo Zhou Zhepeng Zhang Pengfei Yang Yuping Shi Porun Liu Qing Zhang Peng Gao Yanfeng Zhang | 2019 | Nano Research2019，12，1： | 4 |

| 6 | Cobalt-doped Mn3O4 nanocrystals embedded in graphene nanosheets as a high-performance bifunctional oxygen electrocatalyst for rechargeable Zn–Air batteries显示文摘A non-noble-metal bifunctional catalyst with efficient and durable activity towards both the oxygen reduction reaction(ORR)and the oxygen evolution reaction(OER)is crucial to the development of rechargeable Zn-air batteries.Herein,a facile one-step hydrothermal method is reported for the synthesis of a high-performance bifunctional oxygen electrocatalyst,cobalt-doped Mn_(3)O_(4) nanocrystals supported on graphene nanosheets(Co–Mn_(3)O_(4)/G).Compare to pristine Mn_(3)O_(4),this Co–Mn_(3)O_(4)/G exhibits greatly enhanced electrocatalytic activity,delivering a halfwave potential of 0.866 V for the ORR and a low overpotential of 275 mV at 10 mA cm^(-2) for the OER.The zinc-air battery built with Co–Mn_(3)O_(4)/G shows a reduced charge–discharge voltage of 0.91 V at 10 mA cm^(-2),an power density of 115.24 mW cm^(-2) and excellent stability without any degradation after 945 cycles(315 h),outperforming the state-of-the-art Pt/C–Ir/C catalyst-based device. | Mengyang Dong Xu Liu Lixue Jiang Zhengju Zhu Yajie Shu Shan Chen Yuhai Dou Porun Liu Huajie Yin Huijun Zhao | 2020 | Green Energy & Environment2020，5，4： | 2 |
| 7 | Operando Converting BiOCl into Bi_(2)O_(2)(CO_(3))_(x)Cl_(y) for Efficient Electrocatalytic Reduction of Carbon Dioxide to Formate显示文摘Bismuth-based materials(e.g., metallic, oxides and subcarbonate) are emerged as promising electrocatalysts for converting CO_(2) to formate. However, Bio-based electrocatalysts possess high overpotentials, while bismuth oxides and subcarbonate encounter stability issues. This work is designated to exemplify that the operando synthesis can be an effective means to enhance the stability of electrocatalysts under operando CO_(2)RR conditions. A synthetic approach is developed to electrochemically convert Bi^(O)Cl into Cl-containing subcarbonate(Bi_(2)O_(2)(CO_(3))_(x)Cl_(y)) under operando CO_(2)RR conditions. The systematic operando spectroscopic studies depict that BiOCl is converted to Bi_(2)O_(2)(CO_(3))_(x)Cl_(y) via a cathodic potential-promoted anion-exchange process. The operando synthesizedBi_(2)O_(2)(CO_(3))_(x)Cl_(y) can tolerate-1.0 V versus RHE, while for the wet-chemistry synthesized pure Bi_(2)O_(2)CO_(3),the formation of metallic Bio occurs at-0.6 V versus RHE. At-0.8 V versus RHE, Bi_(2)O_(2)(CO_(3))_(x)Cl_(y) can readily attain a FEHCOO-of 97.9%,much higher than that of the pure Bi_(2)O_(2)CO_(3)(81.3%). DFT calculations indicate that differing from the pure Bi_(2)O_(2)CO_(3)-catalyzed CO_(2)RR, where formate is formed via a *OCHO intermediate step that requires a high energy input energy of 2.69 eV to proceed, the formation of H COO-over Bi_(2)O_(2)(CO_(3))_(x)Cl_(y) has proceeded via a *COOH intermediate step that only requires low energy input of 2.56 eV. | Huai Qin Fu Junxian Liu Nicholas M.Bedford Yun Wang Joshua Wright Peng Fei Liu Chun Fang Wen Liang Wang Huajie Yin Dongchen Qi Porun Liu Hua Gui Yang Huijun Zhao | 2022 | Nano-Micro Letters2022，14，7： | 1 |
| 8 | Enhanced Thermochemical H_2 Production on Ca-Doped Lanthanum Manganite Perovskites Through Optimizing the Dopant Level and Re-oxidation Temperature显示文摘Perovskite material is one of the promising classes of redox catalysts for hydrogen production through two-step thermochemical H20 splitting. Herein, an analogue of La_(1-x)Ca_xMnO_3 perovskite was systematically investigated as a catalyst for thermochemical H2 evolution. The Ca doping level(x = 0.2, 0.4, 0.6, 0.8) and re-oxidation temperature were comprehensively optimized for the improvement of catalytic performance. According to our experimental results, La_(0.6)-Ca_(0.4)MnO_3 perovskite displayed the highest yield of H2 at the re-oxidation temperature of 900℃ and the obtained H2 production was-10 times higher than that of the benchmark ceria catalyst under the same experimental condition. More importantly, La_(0.6)Ca_(0.4)MnO_3 perovskite catalyst exhibited impressive cyclic stability in repetitive O_2 and H_2 test. | Lulu Wang Mohammad Al-Mamun Porun Liu Yu Lin Zhong Yun Wang Hua Gui Yang Huijun Zhao | 2018 | Acta Metallurgica Sinica(English Letters)2018，31，4： | 1 |

| 13 | The role of electrolyte acid concentration in the electrochemical exfoliation of graphite:Mechanism and synthesis of electrochemical graphene oxide显示文摘Electrochemistry has emerged as a major route for graphene and graphene oxide synthesis from graphite.Anodic graphite oxidation is commonly used with dilute mineral acid or aqueous salt electrolytes.In this system,the electrolyte acid concentration appears to be a critical parameter.However,the effect of the acid concentration,particularly at low concentrations,is still not fully understood.To address this issue,we used a packed bed electrochemical reactor to synthesize seven different electrochemical graphite oxide(EGO)products in 2–16M sulfuric acid.Detailed XRD,XPS,Raman,conductivity and optical microscopy analysis of the products was carried out.We found dilute acid(<10 M)graphite oxides were less crystalline and less oxidized than those produced in stronger acids.The oxygen evolution reaction at the graphite surface appears to affect the structural changes,oxidation mechanism,and electrochemical corrosion of the anode.EGO conductivity is also strongly affected by the electrolyte’s acidity.We show that well oxidized,yet reasonably conductive,single layer graphene oxide can be produced from 7.1M acid.These results broaden our understanding of graphite electrochemistry and will serve to inform future electrochemical graphene synthesis efforts. | Sean E.Lowe Ge Shi Yubai Zhang Jiadong Qin Lixue Jiang Shuaiyu Jiang Mohammad Al-Mamun Porun Liu Yu Lin Zhong Huijun Zhao | 2019 | Nano Materials Science2019，1，3： | 1 |
| 14 | Operando reconstruction-induced CO_(2)reduction activity and selectivity for cobalt-based photocatalysis显示文摘The oxygen atom coordination inducing the structure reconstruction of the catalytic site is identified and recognized ambiguously,which is related to accurately declare the mechanism in a dynamic catalytic process.Herein,we demonstrated that the reconstructed catalytic sites would lead to a remarkable performance for photocatalytic CO_(2)reduction.At the initial 4-cycles testing,the in-situ formation of CoOx active sites on the Co(CoP)surface performed an increasing transient activity and selectivity toward CO evolution.The formation of reconstructive Co-O bond and the appearance of intermediate specie CO were simultaneously observed by the pre-operando Raman,revealing the dynamic relationship between catalytic site structure and the photocatalytic properties.Moreover,density functional theory calculations showed that the electronic structure of the reconstructive surface sites could modulate the ability of CO_(2)adsorption and CO desorption.The reduced barrier energy for the rate-determining step finally improved the activity and selectivity of CO_(2)reduction. | Kun Zhao Weiying Pang Shuaiyu Jiang Canyu Hu Porun Liu Dandan Cui Xuefei An Baojuan Tian Chao Gao Pan Zhang Meng Tian Dong Fu Huijun Zhao | 2023 | Nano Research2023，16，4： | 1 |
| 15 | Molten salt assisted fabrication of Fe@Fe_(SA)-N-C oxygen electrocatalyst for high performance Zn-air battery显示文摘Non-noble-metal-based electrocatalysts with superior oxygen reduction reaction(ORR)activity to platinum(Pt)are highly desirable but their fabrications are challenging and thus impeding their applications in metal-air batteries and fuel cells.Here,we report a facile molten salt assisted two-step pyrolysis strategy to construct carbon nanosheets matrix with uniformly dispersed Fe_(3) N/Fe nanoparticles and abundant nitrogen-coordinated Fe single atom moieties(Fe@Fe_(SA)-N-C).Thermal exfoliation and etching effect of molten salt contribute to the formation of carbon nanosheets with high porosity,large surface area and abundant uniformly immobilized active sites.Aberration-corrected high-angle annular dark-field scanning transmission electron microscopy(HAADF-STEM)image,X-ray absorption fine spectroscopy,and X-ray photoelectron spectroscopy indicate the generation of Fe(mainly Fe_(3) N/Fe)and Fe_(SA)-N-C moieties,which account for the catalytic activity for ORR.Further study on modulating the crystal structure and composition of Fe_(3) N/Fe nanoparticles reveals that proper chemical environment of Fe in Fe_(3) N/Fe notably optimizes the ORR activity.Consequently,the presence of abundant Fe_(SA)-N-C moieties,and potential synergies of Fe_(3) N/Fe nanoparticles and carbon shells,markedly promote the reaction kinetics.The as-developed Fe@Fe_(SA)-N-C-900 electrocatalyst displays superior ORR performance with a half-wave potential(E_(1/2))of 0.83 V versus reversible hydrogen electrode(RHE)and a diffusion limited current density of 5.6 mA cm^(-2).In addition,a rechargeable Zn-air battery device assembled by the Fe@Fe_(SA)-N-C-900 possesses remarkably stable performance with a small voltage gap without obvious voltage loss after500 h of operation.The facile synthesis strategy for the high-performance composites represents another viable avenue to stable and low-cost electrocatalysts for ORR catalysis. | Wenjun Zhang Kaicai Fan Cheng-Hao Chuang Porun Liu Jian Zhao Dongchen Qi Lingbo Zong Lei Wang | 2021 | Journal of Energy Chemistry2021，30，10： | 0 |
