Abstract

Ag nanoparticles with surface Cl− modification (Ag–Cl NPs) by in situ electroreduction of AgCl exhibit a high selectivity for CO2-to-CO conversion. The observed C–Cl bond suggests that electrons can be effectively transferred from the Cl− ions to the unoccupied orbital of CO2, and then activate nonpolar CO2 molecules on Cl− sites.
