Abstract

Oxygen evolution reaction(OER)is a kineti-cally harsh four-electron anode reaction that requires a large overpotential to provide current and is of great importance in renewable electrochemical technique.Ir/Ru-based perovskite oxides hold great significance for appli-cation as OER electrocatalysts,due to that their multi-metal-oxide forms can reduce the use of noble metals,and their compositional tunability can modulate the electronic structure and optimize OER performance.However,high operating potentials and corrosive environments pose a serious challenge to the development of durable Ir-based and Ru-based perovskite electrocatalysts.Tremendous efforts have been dedicated to improving the Ir/Ru-based perovskite activity to enhance the efficiency;however,progress in improving the durability of Ir/Ru-based per-ovskite electrocatalysts has been rather limited.In this review,the recent research progress of Ir/Ru-based per-ovskites is reviewed from the perspective of heteroatom doping,structural modulation,and formation of heterostructures.The dissolution mechanism studies of Ir/Ru and experimental attempts to improve the durability of Ir/Ru-based perovskite electrocatalysts are discussed.Challenges and outlooks for further developing Ru-and Ir-based perovskite oxygen electrocatalysts are also pre-sented.
