Abstract
The electrochemical reduction of carbon dioxide (CO2RR) has emerged as a promising approach to mitigate greenhouse gas emissions while simultaneously producing value-added chemicals and fuels. Among the various conversion strategies, electrochemical conversion stands out as inherently advantageous, as it can directly integrate electricity generated from renewable sources while operating under mild reaction conditions. However, the stability of the CO2 molecule requires efficient electrocatalysts to lower its activation barrier and guide the reaction toward selective products. Copper (Cu) has attracted significant interest due to its unique ability to catalyze the formation of hydrocarbons and oxygenates, while silver (Ag) is known for its high selectivity toward carbon monoxide.
Combining these two elements in bimetallic systems represents a potential strategy to enhance the activity and selectivity for the CO2RR
