电催化析氧反应过渡金属硫化物催化剂研究进展

析氧反应（oxygen evolution reaction, OER）、析氢反应（hydrogen evolution reaction, HER）和氧还原反应（oxygen reduction reaction, ORR）为电解水、金属-空气电池等能源器件的半反应。其中，OER由于涉及4e^-转移和O-O键的形成而导致反应动力学迟缓和过电势高，因此，开发优异的OER电催化剂能够有效提高能量转换效率。到目前为止，过渡金属硫化物催化剂（transition metal sulfide catalysts, TMSs）被研究人员大量研究和报道，并且取得飞跃发展。介绍在不同电解质中的OER机制，并通过对近几年相关文献的综合归纳，探究TMSs催化剂的组成、导电性、质子传输、缺陷程度、界面化学等多种因素对OER的影响。综述目前过渡金属硫化物电催化剂在OER领域所面临的挑战和研究进展，希望为TMSs的研究者提供借鉴。

Research progress of transition metal sulfide catalysts for electrocatalytic oxygen evolution reduction

Oxygen evolution reaction (OER), hydrogen evolution reaction (HER) and oxygen reduction reaction (ORR) are semi-reactions of energy devices such as water splitting and metal-air batteries. Among them, the OER has sluggish reaction kinetics and high overpotentials due to the involvement of 4e^? transfer and O-O bond formation, so the development of excellent OER electrocatalysts can effectively improve the energy conversion efficiency. So far, transition metal sulfide catalysts (TMSs) have been studied and reported by researchers, and great development has been obtained. The OER mechanisms in different electrolytes are introduced. Through the comprehensive induction of relevant literature in recent years, the effects of various factors such as composition, conductivity, proton transport, defect degree and interface chemistry of TMSs on OER are explored. The challenges and research progress of transition metal sulfide electrocatalysts in the field of OER are reviewed, hoping to provide reference for researchers of TMSs.
