1Enhanced CO catalytic oxidation by Sr reconstruction on the surface of LaxSr1-xCoO3-δ显示文摘Surface electronic structure of solid materials plays a critical role in heterogeneous catalysis. However,surface chemical composition of the perovskite oxides is usually dominated by segregated A-site cations and the amount of oxygen vacancies is relatively low, which seriously restricts their catalytic oxidation property. Here, we prepare perovskite La_xSr_(1-x)CoO_(3-δ)(x = 0.3, 0.5, 0.7) with different Sr doping amount and experiment results show that perovskite LSCO with higher content of surface Sr possesses more oxygen vacancies and better catalytic activity. On this basis, we develop a new experimental strategy to create more surface oxygen vacancies to promote their CO catalytic activity. In this method, we use high active hydrogen atoms(BH^(4-)) as reductant to realize surface in-situ chemical composite modification of La_xSr_(1-x)CoO_(3-δ)(x = 0.3, 0.5, 0.7), which causes their surface reconstruction(surface Sr enrichment).The regulation mainly focuses on the atomic layer level without damaging their bulk phase structure.Different from traditional high temperature annealing under reducing atmosphere, this method is high-efficiency, green and controllable. Furthermore, we study the surface reconstruction process and demonstrated that it is atomic layer engineering on the surface of La_xSr_(1-x)CoO_(3-δ)(x = 0.3, 0.5, 0.7) by X-ray photoelectron spectroscopy(XPS) and X-ray absorption fine structure(XAFS). Our experiment results also show that these samples treated by this method exhibit superior activity for CO oxidation compared with original samples.Xiyang Wang Keke Huang Jingyu Qian Yingge Cong Chengda Ge Shouhua Feng 2017Science Bulletin2017,62,9:5
2Hydrothermal synthesis and characterization of rare-earth ruthenate pyrochlore compounds R_2Ru_2O_7(R=Pr_(3+),Sm(3+)-Ho(3+))显示文摘A series of pyrochlore oxides, R2Ru2O7 (R=Pr3+, Sm3+–Ho3+) were synthesized under mild hydrothermal conditions. All the samples crystallize in uniform octahedron characteristically. The products were characterized by powder X-ray diffraction, scanning electron microscopy, energy-disperse X-ray spectroscopy, and dc susceptibility, and the factors that affected the crystallization were discussed. It was found that the purity of products depends strongly on the raw materials and the amount of alkalinity in the initial reaction mixtures. The ZFC and FC susceptibilities of all of the compounds R2Ru2O7 at low temperature were also measured and discussed.YAO LinRan, WANG Dong, PENG Wen, HU WeiWei, YUAN HongMing & FENG ShouHua State key Laboratory of Inorganic Synthesis and Preparative Chemistry College of Chemistry, Jilin University, Changchun 130023, China 2011Science China Chemistry2011,54,6:3

4Coordination engineering of cobalt phthalocyanine by functionalized carbon nanotube for efficient and highly stable carbon dioxide reduction at high current density显示文摘Coordination engineering can enhance the activity and stability of the catalyst in heterogeneous catalysis.However,the axial coordination engineering between different groups on the carbon carrier and molecular catalysts in the electrocatalytic carbon dioxide reduction reaction(CO_(2)RR)has been studied rarely.Through coordination engineering strategy,a series of amino(NH_(2)),hydroxyl(OH),and carboxyl(COOH)groups functionalized carbon nanotubes(CNT)immobilized cobalt phthalocyanine(CoPc)catalysts are designed.Compared with no groups,OH groups and COOH groups,NH_(2)groups can effectively change the coordination environment of the central metal Co,thereby significantly increasing the turnover frequency(TOF)(31.4 s^(-1)at-0.6 V vs.RHE,CoPc/NH_(2)-CNT>CoPc/OH-CNT>CoPc/COOH-CN>CoPc/CNT).In the flow cell,the CoPc/NH_(2)-CNT catalyst has high carbon monoxide(CO)selectivity at high current density(~100%at-225 mA·cm^(-2),~96%at-351 mA·cm^(-2)).Importantly,the CoPc/NH_(2)-CNT catalyst can operate stably for 100 h at 225 mA·cm^(-2).Theoretical calculations reveal that CoPc/NH_(2)-CNT catalyst is beneficial to the formation of^(*)COOH and desorption of^(*)CO,thus promoting CO_(2)RR.This work provides an excellent platform for understanding the effect of coordination engineering on electrocatalytic performance and promotes a way to explore efficient and stable catalysts in other applications.Hongdong Li Yue Pan Zuochao Wang Yaodong Yu Juan Xiong Haoyang Du Jianping Lai Lei Wang Shouhua Feng 2022Nano Research2022,15,4:2

6Novel internal photoemission in manganite/ZnO heterostructure显示文摘A novel photovoltaic phenomenon of internal photoemission was found in a low cost manganite La0.62Ca0.29K 0.09MnO3 (LCKMO)/zinc oxide (ZnO) heterojunction bilayers grown on ITO substrate by pulsed laser deposition (PLD) at relative low growth temperature. The heterostructure ITO/LCKMO/ZnO/Al exhibits reproducible rectifying characteristics and light current under continuous laser irradiation of = 325 nm. We report here the influence of LCKMO/ZnO bilayers' thickness on the electrical and photoelectric properties of the heterostructure at room temperature. The power conversion efficiency (PCE) is achieved when the LCKMO and ZnO layers are thin enough or the full space charge layer is sufficient. We obtained the maximum value of PCE of 0.0145% when the thicknesses of LCKMO and ZnO layers are 25 and 150 nm, respectively. The open circuit voltage is 0.04 V under this condition due to the internal photoemission.ZHANG JiaQi HUANG KeKe SI WenZhe WU XiaoFeng CHENG Gang FENG ShouHua 2013Science China Chemistry2013,56,5:2
7Hydrothermal Synthesized Co-Ni3S2 Ultrathin Nanosheets for Efficient and Enhanced Overall Water Splitting显示文摘We used the one-step hydrothennal controlled synthesis method for Co-Ni3S2 ultrathin nanosheets grown directly on nickel foam(NF).The as-synthesized Co-Ni3S2/NF showed eiilianced activities in the hydrogen evolution reaction(HER),oxygen evolution reaction(OER)and better overall water splitting(OWS)efficiency than the iin-doped Ni3S2/NF.the voltage of Co-Ni3S2/NF for OWS was only 1.58 V at the current density of 10 niA/cm^2 and with long time(>30 h)current output during the current-density(i-t)test.The good i-t pertonnance was also observed in both HER and OER processes.Additionally,the Co-Ni3S2/NF showed a large current density(>1A/cm^2)for both HER and OER.Wlien the current densities reached 100 and 1000 mA/cm^2,the required overpotentials tor Co-Ni3S2/NF were 0.35 and 0.75 V for OER and 0.30 and 0.85 V for HER.Therefore,after introducing Co,the activity of Ni3S2-based material was strongly enhanced.JIAN Juan YUAN Long LI He LIU Huanhuan ZHANG Xinghui SUN Xuejiao YUAN Hongming FENG Shouhua 2019Chemical Research in Chinese Universities2019,35,2:2
8Defect-engineered Mn_(3)O_(4)/CNTs composites enhancing reaction kinetics for zinc-ions storage performance显示文摘The designing of reasonable nanocomposite materials and proper introduction of defect engineering are of great significance for the improvement of the poor electronic conductivity and slow reaction kinetics of manganese-based compounds. Herein, we report manganese-deficient Mn_(3)O_(4) nanoparticles which grow in-situ on highly conductive carbon nanotubes(CNTs)(denoted as DMOC) as an advanced cathode material for aqueous rechargeable zinc-ion batteries(RAZIBs). According to experimental and calculation results, the DMOC cathode integrates the advantages of enriched Mn defects and small particle size. These features not only enhance electronic conductivity but also create more active site and contribute to fast reaction kinetics. Moreover, the structure of DMOC is maintained during the charging and discharging process, thus benefiting for excellent cycle stability. As a result, the DMOC electrode delivers a high specific capacity of 420.6 m A h g^(-1) at 0.1 A g^(-1) and an excellent cycle life of 2800 cycles at 2.0 A g^(-1) with a high-capacity retention of 84.1%. In addition, the soft-packaged battery assembled with DMOC cathode exhibits long cycle life and high energy density of 146.3 Wh kg^(-1) at 1.0 A g^(-1) . The results are beneficial for the development of Zn/Mn_(3)O_(4) battery for practical energy storage.Xiuli Guo Hao Sun Chunguang Li Siqi Zhang Zhenhua Li Xiangyan Hou Xiaobo Chen Jingyao Liu Zhan Shi Shouhua Feng 2022Journal of Energy Chemistry2022,31,5:1

17Microwave Assisted Hydrothermal Way Towards Highly Crystalized N-Doped Carbon Quantum Dots and Their Oxygen Reduction Performance显示文摘We proposed a green microwave-assisted hydrothermal way to synthesize highly crystalized N-doped carbon quantum dots(N-CQDs).The N-CQDs obtained by this microwave method have good crystalline degree(ID/IG=0.6)and a high molar ratio of N/C(11.1%)comparing with those obtained from traditional top-down method.The experimental results show that glycerine plays a key role ill the fonnation of highly crystalized N-CQDs.The as-prepared N-CQDs have good luminescent property and may be utilized as fluorescent probe to detect ions or mark cells.As the majority of N atoms in the N-CQDs were pyridinic type(64.8%),the as-prepared N-CQDs were used as a catalyst for the oxygen reduction reaction(ORR)electrocatalysis in the anode of the fuel cell(the onset potential is-0.121V),which was a 4e-transfer procedure and the catalyst showed good stability after 100 cycles.HUANG He LIANG Chen SHA Haoyan YU Ying LOU Yue CHEN Cailing LI Chunguang CHEN Xiaobo SHI Zhan FENG Shouhua 2019Chemical Research in Chinese Universities2019,35,2:1
