Abstract: CO2 is one of the main greenhouse gases. Cycloaddition reaction of CO2 as the raw material with epoxides can produce various cyclic carbonates, and it is a relative green and economical and feasible way for CO2 capture and utilization. Porous Hypercrosslinked Polymers Immobilized Ionic Liquids (HCPs-IL) catalyzed CO2 cycloaddition reaction has the advantages of not requiring solvents, metals and co-catalysts. In this review, we summarized the recent research progress on CO2 cycloaddition reaction catalyzed by HCPs-IL, as well as the characteristics of three methods for preparing super-crosslinked polymer solid ionic liquids, such as ionic monomer self-polymerization / copolymerization or crosslinking method, one-step method for formations of ion and crosslinking simultaneously, and post modification method, and 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 analyzed. It is also pointed out that in order to realize the rapid catalysis of the cycloaddition reaction of CO2 with epoxides under normal pressure, theoretical and technical research should be strengthened from the aspects of increasing ionic density, regulating the surface activation functional groups and ionic microenvironment, and reducing the preparation costs.
