二氧化碳转化是减少二氧化碳排放的关键技术之一。由于甲醇被广泛用作塑料和燃料的原料，利用二氧化碳生产甲醇是一种很有前途的减少二氧化碳排放的方法。然而，CO2加氢制甲醇的多相催化剂在高温下受平衡限制，转化率和选择性较低。相反，与多相催化剂相比，有机金属催化剂可以在相对较低的温度下运行。此外，适当的配体设计可以提高有机金属催化剂的活性和选择性。在有机金属催化剂上二氧化碳加氢制甲醇方面，虽然人们对间接合成方法进行了广泛的研究，但最近在直接合成方面取得了重大进展。本文从有机金属催化剂的设计和反应过程两个方面概述了二氧化碳生产甲醇的间接方法和直接方法的现状。
CO2conversion is one of the essential technologies for the reduction of CO2emissions. As methanol is extensively used as a raw material for plastics and fuels, methanol production from CO2is a promising method to reduce CO2emissions. However, heterogeneous catalysts for CO2hydrogenation to methanol suffer from low conversion and selectivity owing to equilibrium limitations at high temperature. In contrast, organometallic catalysts can perform at relatively low temperatures compared with heterogeneous catalysts. Additionally, an appropriate ligand design can improve the activity and selectivity of organometallic catalysts. In CO2hydrogenation to methanol using organometallic catalysts, although extensive research on indirect synthesis methods has been performed, significant progress has recently been made in direct synthesis. This perspective provides an overview of the current state of indirect and direct methods for methanol production from CO2via the design of organometallic catalysts and reaction processes.
