A new method of synthesis of highly active TiO2-containing systems to purify wastewater by photodecomposition of organic substances has been proposed. A number of catalysts with titania nanoparticles homogeneously distributed on the silica support surface have been prepared and investigated. It is shown that the photoactivity for both unpromoted and Au-containing samples increase not only under action of UV-irradiation. The significant growth of kinetic constant of methylene blue degradation is observed under the action of visible light, compared to Degussa P 25.
