摘要

The selective reduction of carbon dioxide (CO2) into high-value-added chemicals is one of the most effective means to solve the current energy and environmental problems, which could realize the utilization of CO2 and promote the balance of the carbon cycle. Formate is one of the most economical and practical products of all the electrochemical CO2 reduction products. Among the many metal-based electrocatalysts that can convert CO2 into formate, Sn-based catalysts have received a lot of attention because of their low-cost, non-toxic characteristics and high selectivity for formate. In this article, the most recent development of Sn-based electrocatalysts is comprehensively summarized by giving examples, which are mainly divided into monometallic Sn, alloyed Sn, Sn-based compounds and Sn composite catalysts. Finally, the current performance enhancement strategies and future directions of the field are summarized.
