Pore-size-controlled silica membranes were prepared using hexaethoxy disiloxane (HEDS) by a “spacer” technique, which is a novel strategy to control the pore size of silica membranes using bridged alkoxides. HEDS-derived silica gel powders prepared with acid and base catalysts were microporous and mesoporous, respectively. HEDS-derived silica membranes prepared from HCl-catalyzed sol showed high H ...
