Abstract Electrochemical reduction of CO 2 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 CO 2 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 CO 2 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 In 2 O 3 cooperated very well in catalyzing the CO 2 electroreduction.
