This paper reviews the methods of preparation of organic-inorganic hybrid membranes based on metal-organic framework(MOFs)materials and their applications in gas separation,pervaporation and nanofiltration.Gas separation mainly covers the separation performance of hybrid membrane materials with H2,CO2,CH4 as well as other mixtures.Pervaporation involves the application of solvent dehydration or removal of organic matter from an aqueous phase.Nanofiltration covers the separation performance of the hybrid membrane materials in the case of small molecules.The role of such hybrid membrane materials in the above applications is highlighted.Finally,this paper sums up the main challenges faced when using these materials,and discusses prospects for the future development of this field.
