Recent Progress in Surface and Interface Engineering for Electrocatalytic CO2 Reduction

Abstract The conversion of CO 2 through CO 2 reduction reaction (CO 2 RR) into valuable products has potential to lessen the greenhouse effect caused by uncontrolled CO 2 emissions. Challenges of CO 2 RR reaction lie in the stabilization of the reaction intermediate and the activation of the inert chemical bond of CO 2 , but the application of CO 2 RR at large scale is limited by the high cost and structural instability of traditional catalysts. By applying CO 2 RR catalyst with delicate structure of stable CO 2 intermediate to industrial production, the problems such as high cost of CO 2 conversion, low catalytic selectivity and poor catalytic efficiency can be effectively solved, showing better application value and significance than traditional catalysts. This review focuses on the defects, and metal‐support interaction (MSI) effect to modify the catalyst and other strategies to enhance the effectiveness of CO 2 reduction. The challenges and prospects from the three perspectives are also discussed to provide suggestions for the designing of efficient CO 2 RR catalysts in the future. This review offers new insights and research perspectives of reducing CO 2 emission through recycling CO 2 , and neutralizing the carbon cycle.
