Structural regulation strategies and advances of antiperovskites in electrocatalysis

Forced by the problems of severe energy crisis, it is urgent to explore high efficiency sustainable energy storage and conversion technologies, particularly for electrolytic water devices and rechargeable zinc-air batteries (ZABs). The efficiency of these two devices is mainly dominated by the half-reactions of hydrogen evolution reaction (HER), oxygen evolution reaction (OER), and oxygen reduction reaction (ORR). The design of efficient multifunctional electrocatalysts is the key for the development of water splitting and rechargeable ZABs. The antiperovskites as a promising family of electrocatalyst with structure flexibility, high electrical conductivity, and excellent electrocatalytic properties. Defining the enhancement mechanism toward HER, OER, and ORR is an urgent problem for the application of antiperovskite in the electrocatalysis field. This review brief introduces the fundamentals of HER/OER/ORR and summarizes the recent progress of antiperovskite materials in electrocatalysis field, including the research on structural regulation strategies of catalytic properties and catalytic mechanism. Based on ex situ/in situ characterized of electrocatalytic mechanism, the future challenges of antiperovskite in electrocatalytic mechanism and intrinsic modulation were prospected. The basic frontier issues are aimed in the field of HER/OER/ORR to provide theoretical guidance for the development of efficient and economical multifunctional electrocatalysts for ZAB and water splitting.
