Presents the preparation and characterization of a mesoporous material where the framework of both the as-synthesized and calcined materials, is composed of ZrO2-doped 25-angstrom TiO2 anatase crystallites. The nanocrystalline framework is structured about a surfactant-templated, disordere porous network with a unifrom pore diamter of 28 angstrom. Air calcination at 450 degrees C removes the surfactant to eyild a mosoporous oslid with surface area of 330 m2/g. The mesoporous framework and TiO2 crystallite size are surprisingly robust, and we observed no substantial structural differences between precalcined and calcined products.
