Metal Organic Framework (MOF)-Based Membranes for Separation Applications

Abstract

Hybrid organic–inorganic porous crystalline materials, i.e., metal organic frameworks (MOFs), are constructed of bridging organic ligands and metal connectors. However, as synthesised MOFs, they are in powder or crystalline form, which is incompatible with real-field applications. To make MOFs most efficient for real field application, it is necessary to embed or load MOF materials with other support materials to use them as in desired applications. MOF-based mixed-matrix polymeric membranes (MMPMs) are taking keen interaction in the field of membrane-based separations because of their high stability and multicyclic ability. MOFs are widely used in gas separations, waste water treatment, marine oil–water separations, desalination, and many more applications. In this chapter, we addressed MOFs-based MMPM-driven separation processes in various areas. We also described the recent report findings that give vital insights into these membrane materials, particularly at separation and their mechanisms to give better insight of MOFs interactions with other foreign analytes, which leads to finding more sustainable and efficient solutions to the current separation technologies.
