将CO2电化学还原为增值产品是一个有趣的领域。以金属有机骨架为碳前驱体，制备了多孔碳负载的MoP纳米粒子，并对该催化剂用于CO2电还原进行了初步研究。结果表明，In掺杂多孔碳负载的MoP纳米粒子具有优异的CO2还原性能。以离子液体1-丁基-3-甲基咪唑六氟磷酸盐为支持电解质时，法拉第效率和电流密度分别达到96.5%和43.8mA·cm（-2）。电流密度高于迄今为止报道的电流密度，具有非常高的法拉第效率。MoP纳米粒子和掺杂的In 2 O3在催化CO2电还原中有很好的协同作用。
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.
