• 化学固二氧化碳
• 顺式环状碳酸酯
• 溴化锌-离子液体
• 复合催化体系 Chemical fixation of CO_2
• cis-Cyclic carbonate
• ZnBr_2 ionic liquid
• Composite catalyst system

Ionic liquid mediated ZnBr_2 system could catalyze the chemical fixation of CO_2 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...
