Mesoporous titania was obtained by gelation from Ti-alkoxide in alcoholic solutions with addition of polymer and/or surfactant. The structure and surface morphology of the gels were characterized by N2-adsorption measurements, scanning electron microscopy and X-ray diffraction. The specific surface area and pore volume of the gels can be increased with addition of hydrophilic polymer such as polyethyleneglycol. Surfactants like cetyltrimetylammoniumchloride are effective to control the pore size and to increase the pore volume and surface area. The surface morphology of the gels can be modified by the mixing method with polymer and/or surfactant. The effects of the templating on pore size distribution, pore shape, surface area and crystallization behaviors have been discussed.
