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.
