摘要

Ionic liquids(ILs),a kind of novel green media composed entirely of cations and anions,have recently attracted considerable attention due to their unique properties such as non-volatility,tunable polarity,high stability and so on.In this work,the latest progress on the fixation and conversion of carbon dioxide(CO_2)using ILs as absorbents,catalysts or promoters has been summarized.The absorption performance of conventional ILs and task-specific ILs was systematically investigated,the conversion of CO_2 with epoxides,propargyl alcohols and amines using ILs was critically evaluated,and the significant advantages in the fixation and conversion of CO_2 using the ILs were demonstrated compared to the conventional absorbents and the catalytic systems without ILs.This research progress may finally lead to building of an in situ fixation-conversion process of CO_2 with ILs.If so,we are near an epoch of the fixation and utilization of CO_2,although there is obviously a long way to go for us to achieve such a goal.
