The synergy between metal alloy nanoparticles (NPs) and single atoms (SAs) should maximize the catalytic activity. However, there are no relevant reports on photocatalytic CO2 reduction via utilizing SAs NPs.

Abstract Electrochemical CO 2 reduction to valuable ethylene and ethanol offers a promising strategy lower emissions while storing renewable electricity. Cu‐based catalysts have shown the potential for ‐to‐ethylene/ethanol conversion, but still suffer from low activity selectivity. Herein, effects of surface interface structures in production are systematically discussed. Both reactions involve three crucial steps: formation intermediate, CC coupling, hydrodeoxygenation C intermediates. For ethylene, key step is which can be enhanced by tailoring catalyst such as sites on facets, Cu 0 /Cu δ+ species nanopores, well optimized molecule–catalyst electrolyte–catalyst interfaces further promoting higher production.
