CO₂ reduction catalysts are an important aspect of global warming prevention. Herein, electrocatalytic CO₂ reduction using Ag_n(NO₃)_n+1 clusters is reported. In contrast to various other Ag catalysts that reduce CO₂ to CO, these Ag_n(NO₃)_n+1 clusters catalyze the electrochemical CO₂ reduction reaction to produce HCOOH, with a Faraday efficiency of 33%. A size effect, the Ag valence stability and inorganic modification are all possible reasons for this drastic change in the selectivity.

气液界面激光烧蚀制备的 Agn(NO3)n+1 簇催化电化学 CO2 还原为 HCOOH

CO ₂还原催化剂是防止全球变暖的一个重要方面。在此，报道了使用Ag _n (NO ₃ ) _{n + 1}簇的电催化CO ₂还原。与将CO ₂还原为CO 的各种其他Ag 催化剂相比，这些Ag _n (NO ₃ ) _{n + 1}簇催化电化学CO ₂还原反应生成HCOOH，法拉第效率为33%。尺寸效应、银价稳定性和无机改性都是选择性发生这种急剧变化的可能原因。
