“…), which seriously have threatened the survival of human beings. Consequently, the capture and utilization of CO 2 has received unprecedented attention in recent years. , Among them, CO 2 cycloaddition reaction holds great promise because of its 100% atomic utilization efficiency and subsequent highly valued cyclic carbonate products. − However, nowadays, industrial routes mainly rely on the traditional TBAB, KI, and other halogen anion nucleophilic reagent homogeneous catalysts, which suffer from low conversion, harsh reaction conditions, and expensive equipment investment . Part of novel catalytic technology based on ionic liquid-based multifunctional homogeneous catalysts is still confronted with high reaction pressure, unsatisfied catalytic efficiency, and homogeneous separation problem. − As a result, developing highly efficient heterogeneous catalysts that can work under mild conditions holds great promise for technological upgrading of CO 2 cycloaddition.…”
