The electrochemical reduction of CO₂ to fuels or valuable chemicals is an attractive method for satisfying the requirements of renewable energy storage and the artificial carbon cycle. In this study, SnS₂ monolayers were applied as a robust catalyst for the electroreduction of CO₂, enabling the efficient production of HCCO⁻ with a high faradaic efficiency of 94 ± 5% and excellent long-term durability (over 80 h). Theoretical studies revealed that the atomic-scale thickness facilitates the hydrogenation of CO₂ to key HCOO^∗ intermediates and the subsequent proton–electron transfer, leading to superior electrocatalytic performance for the production of formate from CO₂.

CO ₂电化学还原为燃料或有价值的化学物质是一种满足可再生能源存储和人工碳循环要求的有吸引力的方法。在这项研究中，SNS _2个单层应用为CO的电还原鲁棒催化剂₂，使高效的生产HCCO的^-具有94±5％的高法拉第效率和优异的长期耐久性（超过80小时）。理论研究表明，原子尺度的厚度有助于将CO ₂氢化成关键的HCOO ^*中间体，并随后进行质子-电子转移，从而为从CO ₂生成甲酸盐提供了卓越的电催化性能。。
