Summary: Isolating propane from propylene is crucial to obtain purified propylene in petrochemical industries. Cryogenic distillation has been used for this purpose, but it is energy-intensive and costly. Membrane technology, particularly mixed matrix membranes with inorganic nanomaterials, has emerged as a promising alternative due to its low energy consumption and high efficiency. Metalorganic frameworks (MOFs) are explored as potential fillers, but polymer plasticization and inadequate compatibility limit their industrial application. Various strategies, including MOF/polymer selection and engineering, have been proposed to enhance the performance of MOF-MMM for propylene separation. This article reviews these strategies and discusses the challenges and future prospects for industrial application.

Summary: The use of mixed matrix membranes (MMMs) comprising metal-organic frameworks (MOFs) has been recognized as an effective strategy for enhancing gas separation efficiency. However, the poor compatibility between the filler and matrix may compromise the separation performance. This study modifies the filler to improve its compatibility with the matrix and enhance the selectivity of CO2 over N-2 and CH4.

Summary: This study prepared mixed matrix membranes (MMMs) by incorporating Cu@Al(bpydc) into a Pebax polymer, which demonstrated excellent performance in separating CO2/CH4 mixture. The hierarchical pores of Cu@Al(bpydc) increased the diffusion of CO2 in the Pebax matrix, while the abundant chemical groups enhanced the selectivity of CO2.

Summary: A study introduced an efficient and less destructive method to cross-link MOFs/PI mixed matrix membranes, significantly improving membrane stability and mechanical strength under relatively mild conditions without destroying membrane structure. The resulting cross-linked membranes showed significantly enhanced CO2 antiplasticization pressure and gas permeability, while also improving gas separation performance.

Summary: Metal organic frameworks (MOFs) are ideal fillers for preparing mixed matrix membranes (MMMs) due to their molecular sieving property. Highly dispersed ZIF-8 nanoparticles with diameter of around 50 nm were prepared by coating isophthalic dihydrazide (IPD) molecular layer onto their surfaces. The modification of IPD greatly enhances the interfacial affinity between ZIF-8 and 6FDA-Durene polyimide (PI) in MMMs, resulting in improved gas permeation performance.

Summary: Mixed-matrix membranes (MMMs) incorporating M-gallate (M = Ni, Co, Mg) MOF particles were fabricated using 6FDA-based polyimides for ethylene/ethane separation. Among the different MOF particles, Ni-gallate(F) showed the best compatibility with the polyimide, resulting in improved C2H4/C2H6 selectivity and permeability.

Summary: CMS/ZSM-5 mixed matrix membranes were prepared and investigated for their morphology and structure. The results showed that ZSM-5 particles were well dispersed in the carbon matrix and maintained their microstructure during pyrolysis. The CMS/ZSM-5 MMMs exhibited outstanding gas permeability without significantly sacrificing selectivity compared to pure CMS membranes. Additionally, the aging of the CMS/ZSM-5 MMMs in a humid environment was studied and the permeability of the aging membrane was partially recovered after thermal treatment.

Summary: Developing forward osmosis membranes with enhanced efficiency is crucial for addressing water scarcity. This study embedded Zn4O(BDC)3 nanoparticles of different sizes into a PES matrix to form porous-matrix membranes as support layers for thin-film composite FO membranes. The results showed that membranes with larger nanoparticle sizes exhibited higher water flux, and these membranes also performed well in long-term seawater desalination experiments.
