1. A titanium dioxide mixed oxide as a photocatalyst, wherein the titanium dioxide mixed oxide has the following features:

  • BET surface area;

    5 to 300 m2/g,a mixed oxide component;

    one or several oxides selected from the group consisting of aluminium, cerium, silicon, tungsten, zinc, zirconium, and mixtures thereofproportions;

    titanium dioxide more than 97.5 wt. %,the mixed oxide component ≧

    0.1 to <

    2 wt. %,the sum of the contents of titanium dioxide and a secondary component at least 99.5 wt. %, each based on the total quantity of the mixed oxides, andthe titanium dioxide content of the primary particles including intergrown rutile and anatase phases.
