Abstract
A novel processing, so-called simultaneous etching method, has been developed for fabrication of mesoporous films with one-dimensional through channels on given porous substrates. One side mirror polished bulk phase-separated glass disk (Vycol glass) was used as the substrate. A precursor film that consisted of needle-like Fe2O3 nano-crystals and SiO2 matrix was formed on the substrate, then the film and the substrate were etched simultaneously. Finally, a silica membrane with mesoporous silica layer with one-dimensional through channels was obtained.
