Abstract
A method for preparing synthetic, semi-crystalline, porous inorganic oxide composition containing a reactive organic silane moiety which is on the surface of pore walls. The composition is prepared from a poly(oxyalkylene) based surfactant and a hydrolyzable organic silane. The surfactant is preferably a poly(ethylene) oxide, a poly(propylene) oxide polymer or mixtures thereof. The organic silane is preferably mercaptopropylsilane. The compositions are particularly useful as adsorbents, and catalysts.
