Abstract

MOF-derived In–Cu bimetallic oxides are highly efficient electrocatalysts for the transformation of CO₂ into CO in an aqueous electrolyte. By controlling In/Cu ratios, the faradaic efficiency of CO could reach 92.1%. The excellent performance is mainly attributed to stronger CO₂ adsorption, higher electrochemical surface area and lower charge transfer resistance.
