CO2加氢制甲酸贵金属非均相催化剂的研究进展OA

Excessive CO2 emissions have caused severe environmental problems.CO2 hydrogenation to formic acid is one of the effective ways to alleviate the greenhouse effect and realize the high-value utilization of carbon resources.Due to their excellent hydrogenation activities,precious metals are widely used in CO2 hydrogenation to formic acid.The research progress in precious metal heterogeneous catalytic systems for CO2 hydrogenation to formic acid in recent years was reviewed.The reaction mechanism was discussed.Focusing on precious metal monometallic catalysts and bimetallic catalysts,the effects of support types,metal-support interactions and bimetallic synergistic regulation on the structure-activity relationships of catalytic systems were thoroughly analyzed.The relevant strategies for optimizing catalytic performances of catalysts were summarized.Based on the current research status,the development direction and optimization path of precious metal heterogeneous catalysts for CO2 hydrogenation to formic acid in the future were prospected.
