The present study attempts to control the micropore size of silica membrane by varying a substituent group in silane precursors. An amorphous silica membrane was produced by thermal decomposition of phenylethoxysilane (PTES) on a γ-alumina coated α-alumina tube with pore size of 6-8nm. For the gas molecules of CO2, N2, CH4 and C3H8, the PTES-derived membrane exhibited higher molecular-sieving property than the membrane formed with tetraethoxysilane (TEOS). Controlling of micropores of silica membrane using phenylethoxysilane as the Si-source was conjectured to result in performance improvements. |
