Abstract:
1. A TiO 2 catalyst structure for catalytic processes at temperatures up to 1000° C. in a form of powder comprising TiO 2 nano-particles in an anatase crystal form doped with phosphorus, wherein the phosphorus is 0.05-5 wt % of the TiO 2 nano-particles, wherein a specific surface area of the nano-particles in the anatase crystal form is from 20 to 120 m 2 /g, wherein the nanoparticles in the anatase form are made by drying and calcination of an intermediate product in a temperature range from 350 to 1000° C. for 1 to 24 hours, wherein the intermediate product is made by addition of a phosphorus compound to a titanium hydrate paste prepared by hydrolysis of titanium oxysulphate.
