摘　　要：碳捕集、利用与封存(CCUS)技术已经成为我国碳中和技术体系的重要组成部分。与工业领域常用的有机胺吸收剂相比,具有低挥发性、高稳定性和位点可设计等优点的功能化离子液体在化学吸收法捕集CO_(2)方面表现出独特的优势。综述了近年来功能化离子液体在CO_(2)捕集领域的研究进展,简述了功能化离子液体的结构分类和合成策略,详细阐述了功能化离子液体与CO_(2)发生化学反应的3类活性位点(氮位点、氧位点和碳位点)及相应捕集机理,并对将来功能化离子液体CO_(2)捕集技术的研究方向进行了展望。Carbon capture,utilization and storage(CCUS)technology has become an important part of China’s carbon neutral technologies.Compared with the organic amine absorbers conventionally used in the industrial field,functional ionic liquids with low volatility,high stability and site designability show unique advantages in CO_(2) capture by chemical absorptions.The research progress of functional ionic liquids for CO_(2) capture in recent years was reviewed.The structural classification and synthesis strategies of functional ionic liquids were briefly described.Three types of active sites(nitrogen site,oxygen site and carbon site)of functional ionic liquids and the corresponding capture mechanisms were described in detail.And the future research directions of CO_(2) capture by functional ionic liquids were prospected.
