英文摘要On the basis of efficient and recyclable criteria for catalytic conversion of CO2 into cyclic carbonates, functionalized polymeric ionic liquids grafted onto the silica (PIL@SiO2) are explored by the polymeric method herein. Among all the prepared PIL@SiO2, the PIL@SiO2 loaded with a high mass fraction (50%) of PIL is the best in catalytic activity, achieving 91% PO conversion, nearly 50% saved than the non-grafted PIL. In addition, the PIL@SiO2 exhibits higher performance than PILs under identical reaction conditions. Subsequent studies concerning recyclability confirm that the as-prepared catalyst is stable after 5 times recycle without obvious loss in activity. This grafting and polymerization process provides an efficient and sustainable way of CO2 conversion in the long term. [GRAPHICS] .
