摘　　要：大气污染问题是关系人民生命健康和经济社会和谐发展的重大问题。因此需要开发高效的吸附材料用于大气污染物的吸附和分离。金属有机骨架材料(MOFs)是一类新型的多孔材料,该材料具有结构多样、孔结构有序、大比表面积和高孔隙率等结构特点。MOFs通过调节有机配体的长度和官能团调节孔径和孔道尺寸,并进行功能化修饰在孔道中引入功能性位点来提高吸附性能和吸附选择性,从而表现出很好的结构稳定性、热稳定性、酸碱稳定性、可回收使用性及再生性等优势,在大气污染物的吸附中表现出优秀的吸附/分离性能。本文综述了以SO_(2),NO_(2),CO,VOCs等大气污染物的吸附去除为目标的MOFs材料,并对未来研究方向和研究前景进行展望。Air pollution is a major issue related to people’s life and health and the harmonious development of economy and society.Metal organic frameworks(MOFs)are a new kind of porous materials with the characteristics of diverse topological structure,ordered pore structure,large specific surface,high porosity,etc.MOFs can improve the adsorption performance and selectivity by adjusting the length and functional groups of organic ligands,the pore size and pore shape,and post-modification of functional sites on the pore.The MOFs show good structural,thermal and acid-base stability,recyclability and regeneration,and have excellent adsorption/separation performance in the adsorption of air pollutants.In this paper,MOFs materials for the adsorption and removal of SO_(2),NO_(2),CO,VOCs and other air pollutants are mainly reviewed,and the future research direction and prospects are discussed.
