摘　　要：纳米多孔材料由于具有显著的纳米尺度空间效应,在吸附以及膜分离领域中受到了极大的关注。作为无机多孔材料的延伸,金属有机框架材料(metal organic framework,MOF),由于其较大的比表面积、较高的孔隙率和孔结构可调的特点被广泛地应用于气相储存分离、液相的吸附分离和催化反应等各个领域。本文对MOF的种类进行了分类,并对MOF材料的合成方法和粒径调控机理进行了比较,其中,重点介绍了溶剂热合成法的优点。同时,系统地总结了MOF材料在吸附分离研究中存在的问题和局限,并对先进的基于MOF材料的复合膜制备技术进行了展望;总结了MOF在气体储存分离、液体吸附分离以及膜分离方面的应用。最后,针对复合膜的制备提出了通过改变MOF合成方式改善MOF材料与有机膜相容性的思路。Nanoporous materials have attracted great attention in the fields of adsorption and membrane separation due to their remarkable nanoscale spatial effects.As an extension of inorganic porous materials,metal organic framework(MOF)has been widely used in gas-phase storage and separation,liquid-phase adsorption separation and catalytic reaction due to its large specific surface area,high porosity and adjustable pore structure.In this paper,the types of MOF are classified,and the synthesis methods and particle size control mechanism of MOF materials were compared.Among them,the advantages of solvothermal synthesis were emphatically introduced.At the same time,the problems and limitations of MOF materials in adsorption separation research were summarized systematically,and the advanced preparation technology of composite membrane based on MOF materials was prospected;the application of MOF in gas storage separation,liquid adsorption separation and membrane separation was summarized.Finally,for the preparation of composite membrane,the idea of improving the compatibility of MOF material and organic membrane by changing the synthesis method of MOF was proposed.
