| Summary: | 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. |
