大气中CO2质量分数于2021年创下历史新高（414.7 μg/g），由此引发的一系列生态环境问题已成为不争的事实。为解决全球变暖的问题，CO2资源化利用势在必行。从CO2利用和甲醇（MeOH）经济性角度看，CO2加氢制备MeOH是一个非常具有发展潜力的能源路线，可作为实现碳中和的关键路径之一。总结了均相体系中以H2作为还原剂，还原CO2制备MeOH的最新进展；围绕CO2直接加氢制备MeOH、经CO2衍生物加氢制备MeOH以及经HCOOH歧化制备MeOH等3条路径，介绍了每条路径中涉及的催化剂体系设计、构?效关系以及反应机理；概述了每条加氢路径存在的不足，并提出了实现工业化CO2加氢制备MeOH需解决的问题。

The concentration of CO2 in the atmosphere reached an all?time high in the 2021(414.7 μg/g), which has caused a series of ecological and environmental problems. In order to solve the problem of global warming, CO2 resource utilization is imperative. From the view of CO2 utilization and methanol (MeOH) economy, the preparation of MeOH by CO2 hydrogenation is a potential energy route, which can be used as one of the key paths to achieve carbon neutrality. The recent progress in preparation of MeOH by reduction of CO2 with H2 as reductant in homogeneous system was summarized.According to the three routes of preparing MeOH by direct hydrogenation of CO2,preparing MeOH by hydrogenation of CO2 derivatives,and preparing MeOH by dissimilation of HCOOH,the catalyst system design,structure?activity relationship and reaction mechanism involved in each route were introduced,and the shortcomings of each hydrogenation route were summarized,the problems needed to be solved in the industrial production of MeOH by CO2 hydrogenation were put forward.
