Abstract: The solubility of carbon dioxide in traditional room-temperature ionic liquids(RTILs), functionalized ionic liquids or task-specific ionic liquids(TSILs), supported ionic-liquid membranes(SILMs) and polymerized ionic liquids(poly(RTILs)) are summarized. The absorption capacity of TSILs is greater than that of RTILs, but the high viscosity of TSILs can be an operational drawback. SILMs show remarkably high selectivity compared to polymeric membranes, however, the instability of SILMs is recognized as a serious problem. This brief survey of the current development on the imidazolium cation ionic-liquid mediated CO2 capture suggests that CO2 capture by ionic liquids is a feasible practice.

Key words: ionic liquid, imidazolium-base ionic liquid, separate and fix CO2
