高效CO₂ 电催化还原生产低碳燃料和有价值的化学品，正成为一个热门的研究课题，其中发展高效电催化剂是关键技术之一。尽管催化材料的研究开发以及作用机理探究等已有越来越多的报道，但在活性、稳定性、选择性以及生产成本等方面，合成的催化剂还远不能满足实际要求，需要持续寻求更新颖的材料与合成技术。近年来，在众多被探索的电催化剂中，金属硫化物表现出优异的电催化性能和应用前景。文章围绕新型金属硫化物催化剂研究的现状进行全面回顾总结，并对未来的研究方向提出展望。

Efficient CO 2 electrocatalytic reduction to produce low-carbon fuels and valuable chemicals becomes a hot topic of research, and the development of high-efficiency electrocatalysts is one of the key technologies. Despite the increasing reports on the research and development of catalytic materials and the reaction mechanisms, synthetic catalysts are far from meeting the actual requirements
in terms of activity, stability, selectivity and production cost. In recent years, among many explored electrocatalysts, metal sulfides
have exhibited excellent electrocatalytic properties and applications. This paper will review and summarize the research status of new
metal sulfide electrocatalysts and put forward the prospects for future research.
