“…There are many factors that affect the formation of MOF membranes, like the concentration of metal and organic ligand reactants, the composition of the reaction solvent, the growth temperature and time, and the chemical properties and structure of the substrate. [ 28 ] So, when synthesizing MOF membranes, the types and chemical properties of the MOF and substrate are considered as a priority. At present, there are still few reports about MOF membranes that are prepared directly on the unmodified carrier substrate by in situ growth.…”

Metal-organic frameworks (MOFs) are porous crystal frameworks constructed by metal clusters and bridging organic ligands. [1] This class of materials not only has a highly tunable and regular pore structure, variable functionality, and internal connectivity, [2] but the superior designability enables them to accommodate the introduction of a variety of functional sites on frames, cavities, and channels. [3] These make them have important applications in many fields, including drug delivery, [4] adsorption, [5] antimicrobials, [6] electron conduction, [7] gas storage, [8] catalysis, [9] sensing, [10] and energy conversion. [11] MOFs were first developed by Hoskins and Robson via connecting discrete metal clusters and reappraising the Zn(CN) 2 and Cd(CN) 2 structure [12] and then termed MOFs in 1995. [13] Recent researches focus on the modulation of MOF chemistry to expending our understanding of the relationship between the MOFs structure, function, and applications. However, the poor adhesion and heterogeneous distribution of powdery MOFs hindered their detection in many applications. So, the development of the commercialization of MOFs was limited. [14] Membrane is a kind of material with small pore size and large specific surface area. [15] A series of structural features facilitate its rapid transfer of matters with the action of external driving forces in the field of biomedical, [16] energy storage, [17] and environmental protection. [18] The preparation of MOFs into membranes will play their role to the maximum extent [14,19] and endow more precisely pore size, pore structure, and molecular-/ion-specific groups with the membranes. [20] MOF membranes are mainly divided into two categories: pure MOF membranes and MOF/polymer hybrid membranes. Pure MOF membranes are the continuous thin layers of MOFs that are formed by growing (or depositing) on a porous support layer and/or inorganic substrate or a porous polymer substrate. These kinds of MOF membranes have the advantages of good thermal stability, high mechanical property, antifouling, antiswelling, and controllable pore structure. [21] As pure MOF membranes are composed of MOFs, the permeability and selectivity are completely determined by the pore sizes of MOFs, which endow pure MOF membranes with significant selectivity. [22] Pure MOF membranes should have the best performance in theory. However, their brittle texture, high cost, and difficulty in chemical modification still limit their practical applications. MOF/polymer hybrid membranes are composite materials that are composed of a dispersed phase (MOFs) and a continuous phase (polymer or another flexible matrix). There are two forms: MOFs embedded in the polymer matrix and MOFs on the surface of the flexible substrate. The thickness is much thicker than the diameter of the embedded porous MOFs; thus, the doped MOFs are surrounded by the polymer matrix. In this case, the selectivity and permeability of the MOF/polymer hybrid membranes are significantly dependent on the properties of the

A direct method is reported for the preparation of zeolitic imidazolate framework (ZIF) membrane on Cu net without any surface modification technologies. The synthetic mechanism can be attributed to the in situ formed Cu‐N interlayer serving as the nucleation sites, which promote the growth of ZIF membrane. The dense polycrystaline membrane shows moderate H2/CH4 separation performance comparable to previous reports. To further eliminate membrane defects, polymer/MOF suspension instead of pure polymer can be used to accurately seal the valley among crystalline grains. As a result, the as‐prepared composite membrane with highly exposed crystal surface shows enhanced H2/CH4 selectivity of 71.0 with little loss in H2 permeance.
