Preparation and Characterization of Polyethersulfone/α-Alumina Nanocomposite Membranes for Hydrogen Separation

Nanocomposite membranes of polyethersulfone (PES) with α-Alumina were synthesized via thermal phase inversion method. The fabricated flat sheet mixed matrix membranes were characterized using permeation test and Scanning Electron Microscopy (SEM) analysis. The results showed that the nanocomposite membrane containing 8 wt% of α-Alumina exhibited considerably and simultaneously increment in permeability of Hydrogen (up to 21 times) and selectivity of Hydrogen over Nitrogen (up to 3.5 times) . The pressure dependence of the gas permeability of the membranes was also investigated
