Abstract: As a country rich in coal,a lot of CO_2 is produced by burning fossil fuels. CO_2 can be transformed into energy products,chemicals or polymer materials through chemical utilization,which is favorable for realizing its resource utilization. From the perspective of direct and indirect utilization of CO_2,the research progress of CO_2 resource utilization was reviewed.. In terms of direct utilization,the direct hydrogenation of CO_2 to methanol and ethanol was emphasized. l Meanwhile,the syntheses of organic carbonates,such as diethyl carbonate,as well as polymerization of CO_2 with epoxide to synthesize degradable polycarbonate were emphasized. In addition,in the aspect of indirect utilization,the research progress of synthesis of dimethyl carbonate from CO_2 via transesterification of ethylene carbonate and hydrogenation of ethylene carbonate to methanol and ethylene glycol was reviewed. Catalysts for direct methanol synthesis from CO_2 hydrogenation mainly include copper-based catalysts and noble metal catalysts. Because of the high cost of noble metals,inexpensive Cu-based catalysts have been studied extensively. The noble metal(Rh,Pd,Ru)-based catalyst system is widely used in the direct synthesis of ethanol from CO_2 hydrogenation,while,inexpensive,active and stable catalysts are needed to be further studied. Cerium-based heterogeneous catalyst is the most widely studied catalyst for the direct synthesis of diethyl carbonate from CO_2 and ethanol,but the yield of DEC is low due to the water produced in the product. No water is produced in the process of coupling reaction between epoxides and CO_2,which can effectively overcome the limitation of thermodynamics. Therefore,the coupling reaction of epoxide and CO_2 is an effective way to prepare DEC. Rare earth ternary catalyst system is mostly used in the copolymerization of CO_2 and epoxides to prepare polycarbonate materials. The conversion of epoxides and the selectivity of polycarbonate are relatively high,and the industrial applications have been realized. Basic catalysts and ion exchange resins with basic groups are used for the transesterification of CO_2 via ethylene carbonate with methanol to synthesize DMC.In addition,copper-based catalysts are the most studied in the hydrogenation of CO_2 via ethylene carbonate to methanol and ethylene glycol,. In summary,the chemical conversion and utilization of CO_2 is an important way for the comprehensive utilization of carbon and oxygen resources of CO_2,which will effectively support China's goal of carbon neutral in the future.
