Preparation and high CO2/CH4 selectivity of ZSM-5/Ethyl cellulose mixed matrix membranes
Materials Research Express, 2021 It is known that natural gas is extracted with a large amount of CO _2 , which reduces the amount of heat generated during the combustion of natural gas. How to remove some of the CO _2 from the natural gas is a problem that needs to be solved.

Tortuous mixed matrix membranes: A subtle balance between microporosity and compatibility
Journal of Membrane Science, 2021 In this work, the effectiveness of metal-organic frameworks (MOFs) with sheet-like morphologies was assessed as function of the MOF microporosity and MOF-matrix compatibility. Zeolitic imidazolate frameworks (ZIFs, a MOF subclass) with sheet-like/platelet morphologies were incorporated in Matrimid/PBI matrices resulting in mixed matrix membranes (MMMs).

Combination of MOFs and Zeolites for Mixed‐Matrix Membranes
ChemPhysChem, 2011 AbstractMixed‐matrix membranes (MMMs) were prepared by combinations of two different kinds of porous fillers [metal‐organic frameworks (MOFs) HKUST‐1 and ZIF‐8, and zeolite silicalite‐1] and polysulfone. In the search for filler synergy, the MMMs were applied to the separation of CO2/N2, CO2/CH4, O2/N2, and H2/CH4 mixtures and we found important ...
