摘　　要：CO_(2)排放是一个严峻的全球性问题,要实现我国双碳战略目标,CO_(2)捕集技术不可或缺.离子液体作为一类新型分离介质,因其特有的低挥发性、良好的气体溶解性和结构可设计性等优势,在CO_(2)捕集分离领域备受关注.重点讨论了近五年来所报道的氨基和非氨基功能离子液体、离子液体复配溶剂、离子液体杂化吸附和膜材料在CO_(2)捕集分离方面的研究进展,总结了氨基、电负性等功能位点对CO_(2)分离性能及机理的影响规律,以及功能离子液体在复配溶剂、吸附和膜材料中发挥的作用,并对离子液体法CO_(2)捕集技术的未来发展方向和前景提出了展望.CO_(2) emission is a serious global problem.CO_(2) capture technology is indispensable to achieve the strategic goals of carbon peaking and carbon neutrality in China.Ionic liquids as new media have attracted much attention in the field of CO_(2) capture and separation due to their unique advantages of low volatility,good gas solubility and structure designability.This review focuses on research progresses of amino and non-amino functionalized ionic liquids,ionic liquid hybrid solvents,ionic liquid modified adsorbents and membranes for CO_(2) capture and separation reported in the past five years.The influence of amino groups and electronegative functional sites on CO_(2) separation performance and mechanism,and the role of functionalized ionic liquids in hybrid solvents,adsorbents and membranes were summarized.Finally,the future development direction and prospect of ionic liquid-based CO_(2) capture technologies were also proposed.
