CO2 hydrogenation to methanol is an important technology for synthesizing green fuels and basic chemical materials,as well asan effective carbon consumption technology and an important part of carbon neutrality technology system,which exhibits remarkablyeconomic and environmental significance. The development of catalysts with high activity,high selectivity,and high stability is of greatimportance for the research of CO2 hydrogenation to methanol technology. Copper-based catalysts have aroused a lot of attention fromacademia and industry. However,due to the chemical inertness of CO2 and the easy side reactions,the activation of CO2 and selectiveconversion to methanol are extremely challenging. Currently,there are still key challenges such as low CO2 conversion,insufficientmethanol selectivity,and catalyst deactivation. Herein,the recent research progresses of copper-based catalysts in CO2 hydrogenation tomethanol were systematically summarized. The reaction thermodynamics,kinetics,and reaction mechanism were analyzed. Catalyst activesites and the advantages/limitations of various carriers and promoters were elaborated. Besides,the influence of water in the reactionatmosphere on the catalyst and the reaction process were discussed. Finally,prospects for innovative research on copper-based catalysts forCO2 hydrogenation to methanol were proposed. This review aims to provide insights for the development of efficient copper-basedcatalysts and the research on reaction processes and mechanisms,thereby promoting the development of CO2 hydrogenation to methanoltechnology.
