A method for increasing permeability in O2/N2 separation with mixed-matrix membranes made of water-stable MIL-101 and polysulfone

Water-stable MIL-101 microcrystals adhere well to polysulfone (PSF) and yield a very robust mixed-matrix MIL-101-PSF membrane for the O-2/N-2 separation with a selectivity of 5-6 and an unsurpassed O-2 permeability increase by a factor of four to above 6 barrer for MIL-101 loadings of 24%.
