Abstract | Silica-based inorganic-organic hybrid membranes have been prepared on porous alpha -Al2O3 substrate (pore size, 2 mum) using tetraethoxysilane (TEOS) and phenyltrimethoxysilane (PTMOS) as precursors. The effects of sol synthesis conditions on the processing and performance of deposited hybrid layers were observed. The thickness of the hybrid layers after three deposition cycles is about 2 mum, estimated from their cross-section SEM micrographs. The gas permselectivity of the hybrid membrane was characterized by O-2/N-2, CO2/N-2, and CO2/O-2 mixing gases, which was mainly governed by the surface diffusion at lower pressures and Knudson diffusion at higher pressures. The introduction of phenyl groups can not only improve the selectivity of O-2/N-2 and CO2/N-2, but also densify the membrane network.; Silica-based inorganic-organic hybrid membranes have been prepared on porous alpha -Al2O3 substrate (pore size, 2 mum) using tetraethoxysilane (TEOS) and phenyltrimethoxysilane (PTMOS) as precursors.
