Abstract

The impact of cations in the local reaction environment has garnered attention as a crucial factor in tailoring the selectivity of CO2 reduction, although the mechanism remains under debate. Understanding these cation effects through first-principles computations can facilitate the design of efficient reaction networks and gas diffusion layers in electrolyzers. In this minireview, the latest insights into cation effects on CO2 reduction reactions are presented, covering aspects such as tuning the interfacial electric field, coordinating reaction intermediates, altering the interfacial water structure, and modulating local CO2 concentration and pH. Future research directions in this area are also discussed.
