Gas separation and purification using polymeric membranes is a promising technology that constitutes an energy-efficient and eco-friendly process for large scale integration. However, pristine polymeric membranes typically suffer from the trade-off between permeability and selectivity represented by the Robeson's upper bound. Mixed matrix membranes (MMMs) synthesized by the addition of porous nano-fillers into polymer matrices, can enable a simultaneous increase in selectivity and permeability. Among the various porous fillers, metal-organic frameworks (MOFs) are recognized in recent days as a promising filler material for the fabrication of MMMs. In this article, we review representative examples of MMMs prepared by dispersion of MOFs into polymer matrices or by deposition on the surface of polymeric membranes. Addition of MOFs into other continuous phases, such as ionic liquids, are also included. CO 2 separation from hydrocarbons, H 2 , N 2 , and the like is emphasized. Hybrid fillers based on composites of MOFs with other nanomaterials, e.g., of MOF/GO, MOF/CNTs, and functionalized MOFs, are also presented and discussed. Synergetic effects and the result of interactions between filler/matrix and filler/filler are reviewed, and the impact of filler and matrix types and compositions, filler loading, surface area, porosity, pore sizes, and surface functionalities on tuning permeability are discoursed. Finally, selectivity, thermal, chemical, and mechanical stability of the resulting MMMs are analyzed. The review concludes with a perspective of up-scaling of such systems for CO 2 separation, including an overview of the most promising MMM systems.

Mixed matrix materials (MMMs) integrating excellent processability from polymers and distinct separation properties from nanofillers are of interest for membrane gas separations, and they are often made into freestanding films (>100 µm) to demonstrate superior gas separation properties. However, they are difficult to fabricate into thin‐film nanocomposite (TFN) membranes due to interfacial incompatibility between polymers and nanofillers. Here TFN membranes based on MMMs (as thin as 200 nm) are successfully developed comprising amorphous poly(ethylene oxide) (aPEO) and UiO‐66‐NH2 enabling strong hydrogen bonds between the two matrices. Increasing the UiO‐66‐NH2 loading unexpectedly decreases CO2 permeability in freestanding films, but it surprisingly leads to the best CO2/N2 separation properties in the membranes at a loading of 10 mass% (CO2 permeance of 2900 GPU and CO2/N2 selectivity of 48). Nanoconfinement significantly influences the morphological and gas separation properties of the MMM layer. The membrane with 10 mass% UiO‐66‐NH2 demonstrates mixed‐gas CO2 permeance of 1400 GPU and CO2/N2 selectivity of 76 in the presence of 1.2 mol% water vapor at ≈23 °C, surpassing Robeson's upper bound. The membrane also demonstrates stable CO2/N2 separation performance when challenged with real flue gas for 700 h continuously.

effective approach to greatly improve gas separation performance of MMMs.Recently, rigid microporous polymer membranes with high FFV and good interface compatibility, acting as highspeed gas transport channels, have been under intense research interest for gas separation, [3] but it is difficult to realize large-area fabrication and large-scale applications with some of these complex polymer structures. Similarly, very few MMMs have been fabricated having gas transport channels through the gas selective skin layer of the membrane. Wang and co-workers [4] fabricated high-speed vertically aligned montmorillonite gas transport channels as the selective skin layer of MMMs for CO 2 separations. However, the structural adjustability of the gas-selective porous materials is limited, and multistep MMM fabrication procedures are somewhat complicated.Many porous materials are investigated as dispersed phases, such as zeolites, metal-organic frameworks (MOFs), [5] and covalent organic frameworks (COFs). [6] Among these, MOFs have several advantages such as uniform and highly porous structures, large surface areas, tunable pore channels and controllable properties. Using MOFs as fillers, the interfacial compatibility and morphology between filler particles and polymer matrix can be controlled more easily due to the presence of organic ligands with a broad variety of functionalities on the MOF structures. This superior affinity and compatibility of MOFs with polymer chains make them outstanding fillers to increase gas separation performance of MMMs.To the best of our knowledge, using MOFs as unobstructed and direct gas transport channels through MMMs has rarely Ultrathin unobstructed gas transport channels through the membrane selective layer are constructed in mixed matrix membranes (MMMs) by using gravity-induced interface self-assembly of poly(vinylamine) and polymermodified MIL-101(Cr). For CO 2 /N 2 (15/85 by volume) mixed gas, the MMMs achieve a high CO 2 permeance of 823 gas permeation units and CO 2 /N 2 selectivity of 242 at 0.5 MPa. Based on economic analyses, a two-stage membrane process can achieve gas separation and economic targets.Membrane technology has many advantages, such as operational simplicity, lower energy requirements and environmental friendliness, which have enabled significant commercial advances in the field of gas separation. [1] Mixed matrix membranes (MMMs) are of interest in gas separation applications because they combine the advantages of polymeric dense membranes, such as inexpensive large-scale fabrication, with filler materials of defined pore sizes, allowing high gas permeance and permselectivity to be achieved simultaneously. In many MMMs, porous filler materials are deployed as the dispersed phase within a continuous polymer phase. [2] Currently, most porous materials used in MMMs are encapsulated by polymer matrix, and the filler acts to disrupt regular polymer chain packing, leading to an increase in fractional free volume (FFV) and a decrease in crystallinity. Thus, gas separatio...
