The invention relates to an imidazole grafting-type ionic liquid catalyst, which is hydroxide of 1-propyl (triethoxysilyl)-3-methylimidazole grafted on a carrier. The representation formula of the imidazole grafting-type ionic liquid catalyst is [Smim]OH/X and a mass grafting amount of ionic liquid is between 5 and 25 percent, wherein Smim represents 1-propyl (triethoxysilyl)-3-methylimidazole; and X represents the meso-porous carrier. The imidazole grafting-type ionic liquid catalyst has the advantages of good catalytic effect, high conversion rate of propylene oxide, 100 percent of selectivity of propene carbonate, mild reaction condition and capability of being recycled better.
