abstract = {The electrochemical conversion of CO2 to C2+ products represents a significant technological opportunity for addressing global climate change. Nevertheless, copper-based catalysts continue to present challenges in terms of selectivity and the long-term stability of C2+ products. In this study, we demonstrate that the introduction of a second metal, silver (Ag), onto copper-based catalysts represents an effective strategy for enhancing the selectivity and reactivity of these catalysts in the electrochemical CO2 reduction reaction. This approach involves modulating the adsorption strength or geometry of CO intermediates on the Cu-based catalyst surface. The results demonstrate that the Faradaic efficiency (FE) of C2+ products in the electrochemical CO2 reduction reaction over a 5% Ag/Cu catalyst is 77%–80% within the current density range of 800 to 1000 mA·cm−2. Furthermore, stability tests were conducted on the electrochemical CO2 reduction reaction in a membrane electrolyzer using pure water as the electrolyte. Following a 15 h testing period at a current of −1000 mA, the FE of CO2 reduction was observed to be 45%, indicating favorable stability. This provides a foundation for further research and development in the industrial application of electrochemical CO2 reduction.}
