摘　　要：金属有机骨架(Metal-organic framework,MOF)是具有较高的孔隙率、比表面积及高度可设计性的新型纳米材料,在吸附分离、固相萃取等诸多领域有着广泛应用。离子液体(Ionic liquid,IL)具有稳定性好、功能可设计的特点,它作为新型绿色溶剂有极大的应用前景。将IL负载到MOF的孔隙中,开发新型离子液体改性金属有机骨架(IL/MOF)复合材料,可以充分发挥两种材料的优势。本文讨论了迄今为止IL/MOF复合材料的所有构筑策略及在大气环境介质中捕集分离CO_(2)和去除水环境介质中污染物的应用和优势,并对未来IL/MOF复合材料在环境介质中的应用方面进行了总结和展望。Metal-organic framework(MOF)is a new type of nanomaterials with high porosity,specific surface area and high designability,which has been widely used in many fields such as adsorption separation and solid phase extraction.Ionic liquid(IL)have good stability and functional design,which have great application prospects as new green solvents.Loading ILs into the pores of MOFs to develop new IL/MOF composites can give full play to the advantages of the two materials.In this review,we discussed all the construction strategies of IL/MOF composites so far,as well as the application and advantages of CO_(2)capturing and separating in atmospheric environment and removing pollutants in water environment.We also summarized and prospected the application of IL/MOF composites in environmental media in the future.
