Electric-Field-Treated Ni/Co3O4 Film as High-Performance Bifunctional Electrocatalysts for Efficient Overall Water Splitting
文献摘要：
Rational design of bifunctional electrocata-lysts for oxygen evolution reaction(OER)and hydrogen evolution reaction(HER)with excellent activity and stabil-ity is of great significance,since overall water splitting is a promising technology for sustainable conversion of clean energy.However,most electrocatalysts do not simultane-ously possess optimal HER/OER activities and their elec-trical conductivities are intrinsically low,which limit the development of overall water splitting.In this paper,a strat-egy of electric field treatment is proposed and applied to Ni/Co3O4 film to develop a novel bifunctional electrocatalyst.After treated by electric field,the conductive channels con-sisting of oxygen vacancies are formed in the Co3O4 film,which remarkably reduces the resistance of the system by almost 2×104 times.Meanwhile,the surface Ni metal electrode is partially oxidized to nickel oxide,which enhances the catalytic activity.The electric-field-treated Ni/Co3O4 material exhibits super outstanding performance of HER,OER,and overall water splitting,and the catalytic activity is significantly superior to the state-of-the-art noble metal catalysts(Pt/C,RuO2,and RuO2 ‖ Pt/C couple).This work provides an effective and feasible method for the development of novel and efficient bifunctional electrocatalyst,which is also promising for wide use in the field of catalysis.
