| 1 | Cu Nanoparticles Embedded in N-Doped Carbon Materials for Oxygen Reduction Reaction显示文摘Summary of main observation and conclusion Development of eco-friendly,cost-effective,and high-performance electrocatalysts to replace precious metal platinum for oxygen reduction reaction(ORR)has received increasing attention.Herein,we adopt a facile one-pot strategy to embed Cu nanoparticles onto N-doped carbon-graphene(Cu@NC-700).The Cu@NC-700 exhibits robust and efficient ORR catalysis with positive half-wave potential(-0.86 V vs.RHE)and lowTafel slope(33.9 mV-dec^-1)in 0.1 M KOH solution.Meanwhile,it manifests remarkable electrochemical stability,and strong tolerance to methanol crossover and carbon monoxide poisoning.The synergistic effect between Cu-N-C sites,Cu nanoparticles,and N-doped carbon support speeds up ORR electrocatalysis. | Xudong Wen Hui Qi Yan Cheng Qiaoqiao Zhang Changmin Hou Jingqi Guan | 2020 | Chinese Journal of Chemistry2020，38，9： | 5 |

| 4 | Diagenesis and diagenetic stages prediction of Ed2 reservoir in the west of Bozhong sag显示文摘Diagenesis of clastic rock and hydrocarbon generating capacity are closely related with diagenetic stages.Based on diagenetic evolution,reservoir diagenetic stages prediction method is proposed through making a contrastive study of simulation results and test results using core measurement data.The essence of this method is illustrated and its effectiveness is demonstrated using Ed2 clastic sandstones in the west of Bozhong sag,Bohai Bay Basin,China.Measurement of paleo temperature(T),vitrinite reflectivity(Ro%)and the proportion of smectite in illite/smectite interstratified minerals(I/S-S%)indicate that there are there types of diagenetic stages in the study area,including early diagenetic stage B,middle diagenetic stage A1 and middle diagenetic stage A2.When only considering T index for diagenetic stages prediction,the simulation results are more conservative than measured data with some situations,and the simulation result using Ro%for diagenetic prediction is less than measured data in some wells.When I/S-S%is used,the two situations above both exist.Because depth,temperature,time duration,pressure and some chemical variables can change synchronously or asynchronously,it is difficult to attribute with certainty the parameters that affect the apparent diagenetic stages evolution series.Diagenetic stage variations can be significantly different in different parts of one sedimentary basin.A synthetic indexes method considering T,Ro%,I/S-S%to predict its distribution,and the simulation result has proved that the reliability of the model has greatly improved. | Wendao Qian Taiju Yin Changmin Zhang Guowei Hou Miao He | 2020 | Petroleum2020，6，1： | 1 |

| 6 | A unique Janus PdZn-Co catalyst for enhanced photocatalytic syngas production from CO_(2) and H_(2)O显示文摘The development of excellent catalyst to achieve photocatalytic syngas production from CO_(2) and H_(2)O is a prospective and sustainable strategy to alleviate environment and energy crisis. In this study, a unique Janus PdZn-Co catalyst is prepared by annealed the Pd/IRMOF-3(Co, Zn) precursor. Due to the strong interaction, the electron transfers from PdZn terminal to Co terminal in the Janus structure. The electron-received Co terminal facilitates Co sites coordinate with the electrophilic C atom of CO_(2) and the electron-donated PdZn center is easier to coordinate with nucleophilic O atoms of H_(2)O or C=O bonds.The charge redistribution enhances the absorption of CO_(2) and H2O, which promotes H_(2) evolution and CO production. In addition, the carbon shell effectively suppresses the metal core agglomeration and facilitates the electron transmission from photosensitizer to metallic active sites. Meanwhile, the ratio of CO/H_(2) can be regulated(~3:1 to 2:1) by adjusting the proportion of Co and PdZn. The Janus structure and graphite carbon synergistically play a profound impact on improving the photocatalytic performance.The optimized PdZn-Co catalyst exhibits a superior photocatalytic CO production rate(20.03 μmol/h) and the H_(2) generation rate(9.90 μmol/h) with a ratio of CO/H_(2)= 2.02. | Dongxue Zhou Xiangdong Xue Qingjie Luan Liguo Zhang Baozhen Li Xing Wang Wenjun Dong Ge Wang Changmin Hou | 2023 | Chinese Chemical Letters2023，34，7： | 0 |

| 9 | Interface engineering of Fe-Sn-Co sulfide/oxyhydroxide heterostructural electrocatalyst for synergistic water splitting显示文摘To realize large-scale hydrogen production by electrolysis of water,it is essential to develop non-precious metal catalysts for oxygen evolution reaction(OER)and hydrogen evolution reaction(HER).Here,we fabricate Sn-,Fe-,and Co-based sulfide/oxyhydroxide heterostructural catalyst on nickel foam(FeSnCo_(0.2)S_(x)O_(y)/NF)by solvothermal method.The FeSnCo_(0.2)S_(x)O_(y)/NF requires low overpotentials of 48 and 186 mV at 10 mA·cm^(-2),respectively,for HER and OER.When it is assembled into an electrolytic cell as a bifunctional electrocatalyst,it only needs 1.54 V to reach 10 mA·cm^(-2),far better than IrO_(2)||Pt/C electrolyzer.The formation of sulfide/hydroxide heterostructural interfaces improves the electron transfer and reduces the reaction energy barrier,thus promoting the electrocatalytic processes. | Siyu Chen Ting Zhang Jingyi Han Hui Qi Shihui Jiao Changmin Hou Jingqi Guan | 2024 | Nano Research Energy2024，3，2： | 0 |
| 10 | Improved Energy Conversion Efficiency of ZnO/Polythiophene Solar Cell in Ga-Doped ZnO Nanorod Array Photoanode显示文摘We reported the fabrication and doping effect of Ga-doped ZnO nanorods/electropolymerized polythio-phene(e-PT) hybrid photovoltaic(h-PV) devices. Ga-Doped ZnO nanorod array photoanode devices were fabricatedvia hydrothermally growing nanorods on sol-gel spin-coating ZnO seed layer, and then the nanorod array was im-mersed into a thiophene solution to yield a thin polythiophene film by electrochemically polymerization. Afterwards,a thin layer of A1 was deposited on the surface of polythiophene to make an electrode for photovoltaic measurement.The ZnO nanorods with different Ga-doping contents were characterized by means of X-ray diffraction(XRD), scan-ning electron micrograph(SEM) and X-ray photoelectron spectroscopy(XPS). Photovoltaic J-V characterization wasperformed on the e-PT/ZnO bilayer and bulk heterojunction(BHJ) devices. Though the unsubstituted polythiophene isnot an ideal polymer material for solar cells with high power conversion efficiency, it is a sound model for the studyon the effect of dopant in hybrid materials. The results indicate that doping Ga can substantially improve the powerconversion efficiency of the ZnO-polythiophene solar cell. | WU Jie LIU Huanhuan YUAN Long HOU Changmin | 2016 | Chemical Research in Chinese Universities2016，32，6： | 0 |
| 11 | Surface reconstruction and structural transformation of twodimensional Ni-Fe MOFs for oxygen evolution in seawater media显示文摘As a four-electron transfer reaction,oxygen evolution reaction(OER)is limited by large overpotential and slow kinetics.Here,we in-situ synthesized two-dimensional(2D)Ni-Fe metal-organic framework nanosheets on nickel foam(NixFe-TPA/NF,TPA=terephthalic acid)for oxygen evolution in alkaline and alkaline seawater electrolytes.In 1 M KOH,Ni3Fe-TPA/NF shows a low overpotential(η10)of 189 mV at 10 mA·cm^(-2) and an ultra-low overpotential of only 260 mV at 500 mA·cm^(-2).In alkaline seawater,Ni3Fe-TPA/NF still provides impressive OER performance,with anη10 of 265 mV.In-situ Raman characterization results show that the phase transition occurs during the OER,and Ni3FeOOH with more oxygen vacancies is in-situ formed,reducing the OER energy barrier.Density functional theory(DFT)reveals that the synergy between Ni and Fe reduces the energy barrier and accelerates the rate-determining step.In addition,the ultra-thin 2D sheet structure and the close combination of Ni3FeOOH and highly conductive NF support ensure the high catalytic OER activity.Therefore,the surface reconstruction and structural modification strategy can be used to design and prepare high-performance OER electrocatalysts for energy-related applications. | Liyuan Xiao Xue Bai Jingyi Han Tianmi Tang Siyu Chen Hui Qi Changmin Hou Fuquan Bai Zhenlu Wang Jingqi Guan | 2024 | Nano Research2024，17，4： | 0 |
