Abstract:

Due to the worsening global climate change and the increasing extreme weather events, CO2 capture and separation has important strategic significance and relates to human survival. In recent years, new materials for CO2 capture and separation have emerged. Among them, ionic liquids (ILs), as a new alternative to organic solvents, have received tremendous interest due to the tunable chemical structures and unique physicochemical properties, such as low volatility, high thermal stability and excellent solubility. And metal-organic frameworks (MOFs) have also been considered as fascinating porous materials for CO2 capture and separation. In this paper, the research progress of CO2 capture and separation by ILs/MOFs composites is summarized. The adsorptive separation via MOFs-supported ILs, ILs-modified MOFs, dispersing MOFs in ILs to form porous liquids, and membrane separation are all discussed, as well as the advantages and disadvantages of each method. In addition, the application prospect and development of ILs/MOFs composites in CO2 capture and separation are also discussed.

Key words: metal-organic frameworks, ionic liquids, composite materials, CO2 capture and separation

摘要:

由于全球气候变化加剧和极端天气的增加,CO2捕集分离已经不单单具有重要的战略意义,更关乎人类的生存。近年来,用于捕集分离CO2的新型材料层出不穷,其中,离子液体(ionic liquids,ILs)具有可调变的化学结构和独特的物理化学性质,例如低挥发性、高热稳定性和较好的溶解性,从而引起了广泛关注。同时,金属有机框架结构材料(metal-organic frameworks,MOFs)在CO2捕集分离方面也表现出优异性能。基于此,本文总结了ILs与MOFs相结合的ILs/MOFs复合材料捕集分离CO2的研究进展,主要包括ILs负载于MOFs材料和对MOFs进行改性的吸附分离、MOFs材料分散于ILs中形成多孔液体的吸收分离、膜分离等方法的研究现状,同时,深入探讨了各方法的优点和不足之处,并对ILs/MOFs复合材料在CO2捕集分离中的应用前景和发展趋势进行了展望。
