2Heterogeneous lamellar-edged Fe-Ni(OH)_(2)/Ni_(3)S_(2)nanoarray for efficient and stable seawater oxidation显示文摘Development of efficient non-precious catalysts for seawater electrolysis is of great significance but challenging due to the sluggish kinetics of oxygen evolution reaction(OER)and the impairment of chlorine electrochemistry at anode.Herein,we report a heterostructure of Ni_(3)S_(2)nanoarray with secondary Fe-Ni(OH)_(2)lamellar edges that exposes abundant active sites towards seawater oxidation.The resultant Fe-Ni(OH)_(2)/Ni_(3)S_(2)nanoarray works directly as a free-standing anodic electrode in alkaline artificial seawater.It only requires an overpotential of 269 mV to afford a current density of 10 mA·cm^(-2)and the Tafel slope is as low as 46 m V·dec^(-1).The 27-hour chronopotentiometry operated at high current density of 100 mA·cm^(-2)shows negligible deterioration,suggesting good stability of the Fe-Ni(OH)_(2)/Ni_(3)S_(2)@NF electrode.Faraday efficiency for oxygen evolution is up to〜95%,revealing decent selectivity of the catalyst in saline water.Such desirable catalytic performance could be benefitted from the introduction of Fe activator and the heterostructure that offers massive active and selective sites.The density functional theory(DFT)calculations indicate that the OER has lower theoretical overpotential than Cl_(2) evolution reaction in Fe sites,which is contrary to that of Ni sites.The experimental and theoretical study provides a strong support for the rational design of high-performance Fe-based electrodes for industrial seawater electrolysis.Baihua Cui Zheng Hu Chang Liu Siliang Liu Fangshuai Chen Shi Hu Jinfeng Zhang Wei Zhou Yida Deng Zhenbo Qin Zhong Wu Yanan Chen Lifeng Cui Wenbin Hu 2021Nano Research2021,14,4:7
3Nano-manufacturing of Co(OH)_(2)@NC for efficient oxygen evolution/reduction reactions显示文摘Oxygen evolution and oxygen reduction are considered as essential processes in the energy conversion devices.The progress of cost-effective bifunctional catalysts has become a critical issue to be solved.Here,we report that Co(OH)_(2)@N-doped carbon(NC)was facilely synthesized through the impregnation strategy of metal-organic frameworks derived carbon and cobalt ions.N-doped carbon with porous structure and cobalt hydroxide nanosheets play a synergistic effect role,representing excellent catalytic performance toward oxygen evolution and reduction reactions.The obtained Co(OH)_(2)@NC exhibits remarkable activity in terms of a lower overpotential of 330 mV@10 mA cm^(-2) for OER and a more positive half-wave potential(E_(1/2)=0.84 V)for ORR in alkaline medium,outperforming IrO_(2) and Pt/C.Due to its superior bifunctional catalytic performance,Co(OH)_(2)@NC catalyst is applied into a promising air electrode of Zn-air battery.This presented strategy of impregnation synthesis in this work provides a new design direction for practical electrochemical energy devices.Guanglu Li Chang Liu Zhao Zhang Baihua Cui Yanan Chen Yida Deng Wenbin Hu 2021Journal of Materials Science & Technology2021,,22:0
