摘　　要：室温离子液体具有独特的气体选择溶解性,在二氧化碳(CO2)的捕集和分离中有很好的应用前景。综述了近年来CO2在不同离子液体中的溶解度研究进展,比较了CO2在常规离子液体和功能型离子液体中的不同溶解机制,分析、归纳了向离子液体中引入不同官能团对CO2溶解性能的影响规律,指出了离子液体捕集CO2的未来研究方向。Due to their preferential solubility for specific gases, the room temperature ionic liquids have exhibited excellent application prospects in capture and separation of carbon dioxide. The research progress in solubility of carbon dioxide in different ionic liquids is reviewed, the mechanisms of carbon dioxide dissolution in conventional ionic liquids and task-specific ionic liquids are compared. The effects of different functional groups on the performance of carbon dioxide dissolution are analyzed, and the trend of carbon dioxide capture with ionic liquids is indicated.
