“…Sci. Recently, many other LD MOF material-based membranes with excellent gas adsorption and separation performances were developed, such as Zn 2 (bIm) 4 nanosheet/GO membrane, [153] [Cu 2 (ndc) 2 (dabco)] n nanosheet/ polybenzimidazole membrane, [318] and Cu-BDC nanosheet/ PIM-1 membrane. After a hot-drop coating process, MOF nanosheets were firmly covered on the surface of α-Al 2 O 3 substrate, and the membrane was obtained (Figure 18c), which achieved a high separation factor (SF) of up to 166 for H 2 /CO 2 separation.…”

Low‐dimensional metal–organic frameworks (LD MOFs) have attracted increasing attention in recent years, which successfully combine the unique properties of MOFs, e.g., large surface area, tailorable structure, and uniform cavity, with the distinctive physical and chemical properties of LD nanomaterials, e.g., high aspect ratio, abundant accessible active sites, and flexibility. Significant progress has been made in the morphological and structural regulation of LD MOFs in recent years. It is still of great significance to further explore the synthetic principles and dimensional‐dependent properties of LD MOFs. In this review, recent progress in the synthesis of LD MOF‐based materials and their applications are summarized, with an emphasis on the distinctive advantages of LD MOFs over their bulk counterparties. First, the unique physical and chemical properties of LD MOF‐based materials are briefly introduced. Synthetic strategies of various LD MOFs, including 1D MOFs, 2D MOFs, and LD MOF‐based composites, as well as their derivatives, are then summarized. Furthermore, the potential applications of LD MOF‐based materials in catalysis, energy storage, gas adsorption and separation, and sensing are introduced. Finally, challenges and opportunities of this fascinating research field are proposed.

“…A counter-diffusion method to fabricate a ZIF-8 membrane as a composite on hollow fiber support membranes that was first functionalized with reduced graphene oxide (rGO) membranes via hydrothermal treatment was reported in [122]. Using this approach, 150 nm thin membranes were grown at the interfaces; gas permeation studies on these ultrathin ZIF- support, which exhibited a higher H2 selectivity and thermal stability.…”

Metal–Organic Framework Membranes: From Fabrication to Gas Separation

et al. 2018

Gas membrane-based separation is considered one of the most effective technologies to address energy efficiency and large footprint challenges. Various classes of advanced materials, including polymers, zeolites, porous carbons, and metal–organic frameworks (MOFs) have been investigated as potential suitable candidates for gas membrane-based separations. MOFs possess a uniquely tunable nature in which the pore size and environment can be controlled by connecting metal ions (or metal ion clusters) with organic linkers of various functionalities. This unique characteristic makes them attractive for the fabrication of thin membranes, as both the diffusion and solubility components of permeability can be altered. Numerous studies have been published on the synthesis and applications of MOFs, as well as the fabrication of MOF-based thin films. However, few studies have addressed their gas separation properties for potential applications in membrane-based separation technologies. Here, we present a synopsis of the different types of MOF-based membranes that have been fabricated over the past decade. In this review, we start with a short introduction touching on the gas separation membrane technology. We also shed light on the various techniques developed for the fabrication of MOF as membranes, and the key challenges that still need to be tackled before MOF-based membranes can successfully be used in gas separation and implemented in an industrial setting.
