“…15 -is reported. [341][342][343][344][345] In principle, the lab-scale fabrication procedure of MOF-based MMMs is similar to the one applied for the synthesis of other MMMs. This involves the phase-inversion and solution-casting methods.…”

aThe latest developments in zeolite membranes are reviewed, with an emphasis on the synthesis techniques, including seed assembly and secondary growth methods. This review also discusses the current industrial applications of zeolite membranes, the feasibility of their use in membrane reactors and their hydrothermal stability. Finally, zeolite membranes are compared with metal-organic framework (MOF) membranes and the latest advancements in MOF and mixed matrix membranes are highlighted.

“…CO 2 permeability was increased by 3.6 times by the addition of 35 wt% ZIF-8, while a slight decrease on CO 2 /N 2 selectivity was observed. In other study, an asymmetric membrane was prepared by Li et al [27] by depositing a thin mixed matrix layer of < 1 mm of Pebax 1657 and ZIF-7 on a porous polyacrylonitrile support. An intermediate gutter layer of PTMSP was applied to serve as a flat and smooth surface for coating to avoid polymer penetration into the porous support.…”

A R T I C L E I N F O Keywords:Metal organic frameworks ZIF-94 Mixed matrix membrane CO 2 capture A B S T R A C T Carbon capture and storage (CCS) using membranes for the separation of CO 2 holds great promise for the reduction of atmospheric CO 2 emissions from fuel combustion and industrial processes. Among the different process outlines, post-combustion CO 2 capture could be easily implemented in existing power plants. However, for this technology to become viable, new membrane materials have to be developed. In this article we present the development of high performance mixed matrix membranes (MMMs) composed of ZIF-94 filler and 6FDA-DAM polymer matrix. The CO 2 /N 2 separation performance was evaluated by mixed gas tests (15CO 2 :85N 2 ) at 25°C and 1-4 bar transmembrane pressure difference. The CO 2 membrane permeability was increased by the addition of the ZIF-94 particles, maintaining a constant CO 2 /N 2 selectivity of~22. The largest increase in CO 2 permeability of~200% was observed for 40 wt% ZIF-94 loading, reaching the highest permeability (2310 Barrer) at similar selectivity among 6FDA-DAM MMMs reported in literature. For the first time, the ZIF-94 metal organic framework crystals with particle size smaller than 500 nm were synthesized using nonhazardous solvent (tetrahydrofuran and methanol) instead of dimethylformamide (DMF) in a scalable process. Membranes were characterized by three non-invasive image techniques, i.e. SEM, AFM and nanoscale infrared imaging by scattering-type scanning near-field optical microscopy (s-SNOM). The combination of these techniques demonstrates a very good dispersion and interaction of the filler in the polymer layer, even at very high loadings.

“…Other formation processes are inert gas condensation, spray pyrolysis, laser pyrolysis, flame spray pyrolysis, pulsed laser ablation, spark discharge generation, ion sputtering, photothermal synthesis, thermal plasma synthesis, flame synthesis, low temperature reactive synthesis, mechanical alloying/milling, mechanochemical synthesis, and electro-deposition [43,128]. Li et al [130] recently reported the first mixed-matrix composite membrane made of commercially available poly (amide-b-ethylene oxide) mixed with the nano-sized zeolitic imidazole framework ZIF-7. The ZIF-7 nanoparticles was synthesized and dispersed in a polymer matrix.…”
