摘要

电化学二氧化碳还原反应 (CO2RR)在可再生能源的驱动下将CO2转化为具有高附加值的化学品和燃料, 成为了缓解不断增加的二氧化碳排放和建立碳循环系统的有前景的解决方案。在所有二氧化碳减排产品中, 甲酸或甲酸盐因其在能源和化学工业中的广泛应用、高能量密度以及易于储存、运输和使用而备受青睐。双金属策略能够调节CO2转化为HCOOH的活性和选择性。不幸的是, 低电流密度和稳定性限制了催化剂的工业应用, 这可以通过微调耦合竞争中间体 (COOH* 和 HCOO*) 的吸附来改善, 这非常具有挑战性, 但对于进一步改进催化剂至关重要。最近, 陈教授及其同事进行了密度泛函理论 (DFT) 计算,并通过实验证明了 界面处Sn和Bi的相互作用有利于甲酸盐形成的结构。我们对其进行了亮点评论, 希望通过界面设计策略能够开发其他高性能双金属催化剂。
