摘要：

CO2 is one of the main greenhouse gases, and the cycloaddition of CO2 with epoxides can produce various cyclic carbonates, which is a relative green, economical and feasible way for CO2 capture and utilization. Using porous hypercrosslinked polymers immobilized ionic liquids (HCPs-ILs) to catalyze the CO2 cycloaddition reaction does not require solvents, metals and co-catalysts. In this review, we summarized the recent research progress on CO2 cycloaddition catalyzed by HCPs-ILs, as well as the characteristics of three methods for preparing hypercrosslinked polymer immobilized ionic liquids, namely ionic monomer self-polymerization/copolymerization or crosslinking method, one-step method of simultaneous formation of ions and crosslinking, and post modification method. The problems that are not conducive to the application of "CO2 chemical industry" such as low ionic density, insufficient catalytic efficiency, and high preparation cost were also analyzed. Finally, we pointed out that in order to realize the rapid catalysis of the cycloaddition reaction of CO2 with epoxides under normal pressure, theoretical and technical researches should be strengthened from the aspects of increasing ionic density, regulating the surface activation functional groups and ionic microenvironment, and reducing the preparation costs. © 2021, Chemical Industry Press Co., Ltd.
