摘要
二氧化碳(CO2)的捕获、分离与利用已成为人类共同关心的重要课题。离子液体具有几乎无蒸气压、良好的热稳定性、结构可设计性等独特优点,在CO2吸附分离领域的巨大应用潜力已成共识。因此,综述了近年来离子液体吸附CO2的研究进展。主要介绍了国内外吸收CO2的3类离子液体:功能化离子液体,负载型离子液体及离子液体聚合物。通过阐述它们对CO2的吸附性能及优缺点,指出离子液体聚合物吸附剂用于吸附二氧化碳是一个具有很大潜力的研究方向。
Capturing,separating and utilizing carbon dioxide（CO2）is now extensively concerned in the world.As a potential and environmentally benign solvent in CO2 absorption,ionic liquids provoke a wide interest due to their unique characteristics such as negligible vapor pressure and designable structure.In this review,we would like to address the recent research progresses in absorption and transformation of CO2 using ionic liquids.The paper described the carbon dioxide adsorption materials over domestic and overseas：task-specific ionic liquids,supporting ionic liquids and polymeric ionic liquids（PILs）.At the same time,it also introduced the characteristics of absorption and their advantages or disadvantages,and indicated that PILs have great potential for development.
