Thermal　catalysis　C02　hydrogenation　to　methanol　has　significant　carbon　reduction　effect,　can　effectively　store　renewable　energy,　and　has　broad　prospects　for　industrial　prospect.　In　this　review,　the　reaction　network　for　the　C02　hydrogenation　to　methanol　and　thermodynamic　challenges　were　introduced,　and　the　process　and　its　industrial　applications　at　domestic　and　abroad　were　summarized.　Then　the　research　progress　on　the　catalysts　with　different　active　components　in　recent　years　was　reviewed　from　the　aspects　of　preparation　method,　the　active　sites,　reaction　mechanism　and　kinetics　in　terms　of　problems　and　advantages.　The　structure-activity　relationship　of　copper-based　catalysts,　including　the　effects　of　the　active　components,　support　and　additives　on　the　activity　and　methanol　selectivity,　was　emphatically　described.　A　prospect　was　finally　presented　for　the　catalyst　development　in　the　future.　©　2024　Research　Institute　of　Petroleum　Processing,　SINOPEC.　All　rights　reserved.
