摘要
Electrochemical carbon dioxide reduction reaction (CO2RR) to highly value‐added C2+ fuels or chemicals is a promising pathway to address environment issues and energy crisis. In the periodic table, Cu as only the candidate can convert CO2 to C2+ products such as C2H4 and C2H5OH due to the suitable absorption energy to reaction intermediate. Application of Cu is limited for its low activity and poor selectivity. The tandem catalytic strategy can effectively solve the problems caused by single copper catalyst. In tandem catalysis, how to promote the formation, transport, adsorption and coupling of the important intermediate CO is the key issue to improve the selectivity of C2+ products. Regulating structure of Cu‐based bimetallic can effectively promote processes to Electrochemical CO2RR on account of its synergistic effect, electronic effect. In this review, we systematically summarized the relationship between structure of Cu‐based bimetallic catalysts with performance of electrochemical CO2RR. More importantly, we reveal that different Cu‐based bimetallic structures enhance the activity and selectivity of catalysts by regulating the processes such as the transport and adsorption of reaction intermediate CO. We proposed well‐effective strategies to rationally design Cu‐based metallic catalysts. We put forward some challenges and opportunities that Cu‐based bimetallic catalysts in future.
