Bi/CeO₂-Decorated CuS Electrocatalysts for CO₂-to-Formate Conversion.

ABSTRACT: The electrocatalytic carbon dioxide (CO₂) reduction reaction (CO₂RR) is extensively regarded as a promising strategy to reach carbon neutralization. Copper sulfide (CuS) has been widely studied for its ability to produce C₁ products with high selectivity. However, challenges still remain owing to the poor selectivity of formate. Here, a Bi/CeO₂/CuS composite was synthesized using a simple solvothermal method. Bi/CeO₂-decorated CuS possessed high formate selectivity, with the Faraday efficiency and current density reaching 88% and 17 mA cm^-2, respectively, in an H-cell. The Bi/CeO₂/CuS structure significantly reduces the energy barrier formed by OCHO*, resulting in the high activity and selectivity of the CO_2<
