The electrodeposition of Cu and Zn onto bare CuZn mesh supports offers a straightforward method for fabricating novel electrodes electrochemical CO2 reduction (EC CO2R). This study evaluates the performance these modified by assessing their Faradaic efficiency (FE) under various conditions including different electrolytes, concentrations, applied potentials, recycling effects, Nafion treatment. products were categorized into several groups: C1 gaseous (CO CH4), C2 (C2H4 C2H6), C3,4 hydrocarbons, major C1/C2/C3 liquid (formate, ethanol, propanol), minor (methanol, acetate, acetaldehyde, isopropanol). We evaluated dynamic FE variations experimental conditions. production C2+ hydrocarbons through EC CO2R was found to be analogous conventional Fischer–Tropsch synthesis, highlighting pivotal roles *CO *CHx intermediates. study's insights C1, C2, C3+ product chemistry aid in further development Cu-based electrocatalysts.

Abstract This study employs a chemically controlled strategy to construct few‐atomic‐layer ZnO structure integrated with polyvinylpyrrolidone (PVP) and nanoscale metallic copper on active carbon. Hydrogen‐bond interactions from PVP's N‐vinylpyrrolidone allow retain specific proportion of metal atoms, confining electrons at the Cu/ZnO interface form CuZn nanoalloy clusters. The nanoalloy's dual role in promoting CO adsorption C─C coupling synergistically boosts C 2 H 4 production during electrochemical reduction (ECR). Rapid Cu regeneration further increases adsorbed hydrogen (H ads ) water splitting, achieving remarkable selectivity ≈50.2% stable performance over 10 h. Zn→Cu electron confinement interfacial synergy organic‐oxide‐metal heterojunction underscore catalyst's superior efficiency, offering promising pathway for sustainable ‐to‐C conversion.
