Advances in Sn-Based Catalysts for Electrochemical CO(2) Reduction

The increasing concentration of CO(2) in the atmosphere has led to the greenhouse effect, which greatly affects the climate and the ecological balance of nature. Therefore, converting CO(2) into renewable fuels via clean and economical chemical processes has become a great concern for scientists. Electrocatalytic CO(2) conversion is a prospective path toward carbon cycling. Among the different electrocatalysts, Sn-based electrocatalysts have been demonstrated as promising catalysts for CO(2) electroreduction, producing formate and CO, which are important industrial chemicals. In this review, various Sn-based electrocatalysts are comprehensively summarized in terms of synthesis, catalytic performance, and reaction mechanisms for CO(2) electroreduction. Finally, we concisely discuss the current challenges and opportunities of Sn-based electrocatalysts. [Image: see text]
