Electroreduction is a promising technique for the conversion of CO₂ into fuel or valuable chemicals. In this study, thin-layered SnSe₂ as a robust catalyst for CO₂ electroreduction was reported, efficiently furnishing formate with a high faradaic efficiency of 91 ± 4% and a stable activity for more than 100 h. The promising electrochemical performances of thin-layered SnSe₂ were related to the increased abundance of the exposed active sites, enhanced conductivity, the absence of binders and the presence of selenium promoters in SnSe₂. This work can open new avenues for the development of transition metal dichalcogenide-based electrocatalysts with high efficiency.

二氧化碳在薄层二硒化锡电极上的电解还原成甲酸†

电还原是一种将CO ₂转化为燃料或有价值的化学物质的有前途的技术。在这项研究中，据报道，薄层SnSe ₂作为鲁棒的CO ₂电还原催化剂，以91±4％的高法拉第效率和100多个小时的稳定活性有效地提供了甲酸盐。薄层SnSe ₂的有希望的电化学性能与暴露的活性位点的丰度增加，电导率提高，SnSe _2中不存在粘合剂和硒促进剂有关。这项工作可以为高效过渡金属二卤化硅基电催化剂的开发开辟新的途径。
