Recent Advances in Metal Chalcogenide Catalysts for Electrochemical Carbon Dioxide Reduction

Abstract The electrochemical reduction of carbon dioxide (CO 2 ) into value‐added fuels and chemicals offers a promising pathway for CO 2 recycling. Metal chalcogenide nanostructures—including sulfides, selenides, and tellurides—exhibit significant potential as CO 2 reduction reaction (CO 2 RR) electrocatalysts due to their tunable intermediate adsorption and enhanced conductivity. Their diverse stoichiometries, phases, and morphologies enable the rational design of novel catalytic materials. Advances in metal chalcogenide catalysts have demonstrated notable improvements in CO 2 RR activity and selectivity. This review highlights recent progress in metal chalcogenide design, controlled synthesis, dynamic structural evolution during catalysis, and mechanistic insights into CO 2 RR, providing a blueprint for developing next‐generation high‐performance CO 2 RR electrocatalysts.
