Abstract:
CO2的高效转化利用对缓解能源危机以及实现“碳中和”目标具有重要的战略意义。借助绿色氢气将CO2转化为化工生产的重要原料，不仅助力相关行业实现碳达峰，还将有力助推碳中和目标的实现，因此开发高活性和高稳定性催化剂具有重要意义。本文概述了通过CO2直接加氢合成乙醇的重大进展。开展了关于CO2加氢制乙醇的多相催化剂的研究，如催化剂的活性组分、载体及反应条件等方面进行研究以实现开发具有高活性、高选择性的催化剂。
The efficient conversion and utilization of CO2 has important strategic significance for alleviating the energy crisis and achieving the goal of “carbon neutrality”. The use of green hydrogen to convert CO2 into an important raw material for chemical production will not only help related industries to achieve carbon peaks, but will also help achieve the goal of carbon neutrality. Therefore, the development of high-activity and high-stability catalysts is of great significance. This article outlines the major progress in the synthesis of ethanol through the direct hydrogenation of CO2. Researches on heterogeneous catalysts for the hydrogenation of CO2 to ethanol have been carried out. For example, the active components of the catalyst, the support and the reaction conditions are studied to realize the development of a catalyst with high activity and high selectivity.
