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. [ABSTRACT FROM AUTHOR]

Abstract: Electrochemical reduction of CO2 into value‐added product is an interesting area. MoP nanoparticles supported on porous carbon were synthesized using metal–organic frameworks as the carbon precursor, and initial work on CO2 electroreduction using the MoP‐based catalyst were carried out. It was discovered that MoP nanoparticles supported on In‐doped porous carbon had outstanding performance for CO2 reduction to formic acid. The Faradaic efficiency and current density could reach 96.5 % and 43.8 mA cm−2, respectively, when using ionic liquid 1‐butyl‐3‐methylimidazolium hexafluorophosphate as the supporting electrolyte. The current density is higher than those reported up to date with very high Faradaic efficiency. The MoP nanoparticles and the doped In2O3 cooperated very well in catalyzing the CO2 electroreduction.
