Ag increases local CO coverage, while PVP modulates the electronic structure of Cu\/Ag sites, jointly promoting C\u2013C coupling. This synergistic interface establishes a locally alkaline, carbonate\u2010rich microenvironment that facilitates dual hydrogen\u2010source utilization and enhances ethanol production. The catalyst achieves Faradaic efficiencies of 52.2% for ethanol and 72.2% for total C\n                    <jats:sub>2<\/jats:sub>\n                    products, with stable operation over 12 h.
