Abstract
In this work, we report a more simple and efficient way to synthesize a composite ionic liquid (IL) ([BMIM][Zn2Br5]) by directly coupling the IL with molecular sieves. Two kinds of immobilized catalysts were successfully synthesized: SBA-15-[BMIM][Zn2Br5] and SBA-15-CPTES-[BMIM][Zn2Br5]. The catalysts were used to catalyze the cycloaddition reaction of continuous transformation of CO2 and propylene oxide, and the catalytic performance of catalysts was further studied. Compared with the traditional IL catalysts, the catalysts not only have excellent catalytic performance, but also have a significantly longer service life. This is because the catalysts are formed by a high energy chemical bond of silane between IL catalysts and molecular sieves, which can effectively solve the problem of the loss of IL active components in the catalytic process.
