Description
Summary:Electrocatalytic CO 2 reduction reaction (CO 2 RR) converts CO 2 into valuable chemical fuels, which can effectively alleviate global warming and energy crisis. However, limited by its slow reaction rate and low product selectivity, it is urgent to design efficient, cheap, safe, and highly selective CO 2 RR electrocatalysts. Owing to the advantages of adjustable electronic structure, abundant active sites, low cost, environmental friendliness and excellent electrochemical performance, bimetallic chalcogenides have aroused great interest. Here, we briefly summarized different bimetallic oxides and sulfides for electrocatalytic CO 2 RR in the past five years. In addition, different hybridizations formed between metal atoms, including intermetallic compounds, heterostructures and metal doping, were generalized. Their positive effects on CO 2 RR catalytic selectivity and activity were deeply uncovered. Besides, we also put forward some views about the future research directions and perspectives in CO 2 RR field. This review aims to provide a reference for the rational design of bimetallic chalcogenides towards electrocatalytic CO 2 reduction. Graphical Abstract
