Fabrication and Application of Three Component CuBTC/Graphene Oxide/PSF Membrane for Hydrogen Gas Separation

Metal organic frameworks (MOFs) with excellent properties have showed good attention for different application especially gas adsorption and separation. In this regard, fabrication of MOF hybrids with carbon based materials is new strategy to upgrade MOF performance. In this study CuBTC (Copper benzene-1, 3, 5 tricarboxylic acid)/graphene oxide (GO) composite was synthesized and characterized by BET, FESEM, XRD and FT-IR techniques. Then CuBTC/GO composite were incorporated into polysulfone (PSF) polymer to prepare mixed matrix membranes (MMMs). The obtained membranes were characterized by FESEM, FT-IR and XRD tests and their gas permeability was measured. It was revealed that CuBTC/GO composite performs well as a filler. 15 wt% loading of CuBTC/GO in PSF presented 80.03 and 70.46 for H2/CH4 and H2/N2, selectivity respectively.
