An ionic liquid 1-(triethoxysilyl)propyl-3-methylimidazolium hydroxide ([Smim]OH) was grafted on silica gel with different amount by post-grafting method. Such grafted ionic liquids (GILs), which were verified by means of FTIR, element analysis, Si-29 MAS NMR and N-2 adsorption-desorption could be used as highly effective heterogeneous catalysts toward propylene carbonate synthesis through cycloaddition of CO2 with propylene oxide under solventless and mild conditions.
