【Abstract】 The conversion of CO₂ into high-value chemicals has always been a hot research topic.This paper reviews the research on the conversion and utilization of CO₂ and focuses on the reaction processes and related mechanisms of hydrogenation of CO₂ to methanol,syngas production using CO₂ as oxidant and the cycloaddition of CO₂.The technical characteristics and research direction of the conversion of CO₂ were compared.It is pointed out that broadening the types of CO₂ conversion products,optimal reaction path,selection or design of high efficiency catalysts,catalysis mechanism are the main problems in current research,and the engineering application development is a little backward,which needs to rely on the development of carbon capture,green electricity and green hydrogen.更多还原
