It has been shown that photocatalytic activity, surface electroconductivity, and magnetic susceptibility of TiO2 significantly depend on the character and concentration of f-element’s admixture as well as on the temperature and conditions of its thermo-treating. Admixtures of f-elements with variable valence and relatively smaller ionic radius are more effective to reach higher photocatalytic activity, surface electroconductivity, and magnetic susceptibility. Above mentioned parameters of TiO2 increase with addition of a small amount of f-elements as well as after thermo-treating of a sample at 673–873 K in the reducing medium. Photocatalytic activity, electroconductivity, and magnetic susceptibility decrease on the following conditions: increase of an admixture content, thermo-processing in the oxidizing medium or at higher temperature.
