Description
Recently, the development of bimetallic interfaces has emerged as a promising strategy for enhancing electrocatalytic CO2 electroreduction (CO2ER) efficiently, with selectivity towards energy-dense hydrocarbons. In this study, we report an electrochemically designed silver-decorated copper-dimercapto thiadiazole modified carbon electrode (Ag@Cu-DM), which facilitates a controlled transition from C1to C2liquid products. The optimized electrochemical synthesis method enabled precise control over the polymer-metal interface, promoting strong electronic interactions and charge transfer. The multiple characterizations conducted for the material revealed distinct lattice fringes corresponding to well-defined Cu and Ag phases. The interplay between Cu and Ag, along with the heteroatoms present within the polymer enhances CO2 activation and intermediate stabilization. The developed Ag@Cu-DM catalyst achieved 89 % F.E. for liquid products alone at a low potential of -0.73 V vs RHE and also demonstrated stable electrolysis for upto 8 Hr. 2025 Elsevier Ltd.
