The authors have prepared and characterized a mesoporous material where the framework, of both the as-synthesized and calcined materials, is composed of ZrO{sub 2}-doped 25-{angstrom} TiO{sub 2} anatase crystallites. The nanocrystalline framework is structured about a surfactant-templated, disordered porous network with a uniform pore diameter of 28 {angstrom}. Air calcination at 450 C removes the surfactant to yield a mesoporous solid with surface area of 330 m{sup 2}/g. The mesoporous framework and TiO{sub 2} crystallite size are surprisingly robust, and the authors observed no substantial structural differences between precalcined and calcined products.
