Abstract: Ionic liquid mediated ZnBr₂ system could catalyze the chemical fixation of CO₂ with epoxides with a high selectivity(>98%) and TOF(5 580 h^-1) under mild reaction conditions and the catalyst could be reused five times almost without losing its catalytic activity and selectivity. Besides, the pure cis-cyclic carbonate of cyclohexene oxide was obtained over this catalyst system.

Key words: Chemical fixation of CO₂, cis-Cyclic carbonate, ZnBr² ionic liquid, Composite catalyst system
