Metal–organic framework-derived indium–copper bimetallic oxide catalysts for selective aqueous electroreduction of CO2

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.
