The TiO2 catalyst structure consisting of TiO2 nano-particles in the anatase crystal form, doped with 0.05-5 wt % phosphorus on the TiO2 basis, organized in the circular planar aggregates with the specific surface area ranging from 40 to 120 m2/g, suitable for catalytic processes at the temperature up to 800° C., and the TiO2 catalyst structure of with the morphology of the aggregated compact particles, with the specific surface area from 20 to 40 m2/g, suitable for the catalytic processes at the temperature up to 1000° C. Active substances selected from the group consisting of silver, copper, gold, platinum metals, nickel, molybdenum and metal oxides except for alkaline metals oxides can be applied onto the surface of both types of the structure.
