Use of Titanium Dioxide Mixed Oxide as a Photocatalyst

Abstract

Use of 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, mixed oxide component: one or several oxides from the group comprising aluminium, cerium, silicon, tungsten, zinc and zirconium, proportions: titanium dioxide more than 97.5 wt. %, mixed oxide component ≧0.1 to <2 wt. %, sum of the contents of titanium dioxide and secondary component at least 99.5 wt. %, each based on the total quantity of the mixed oxide, titanium dioxide content of the primary particles containing intergrown rutile and anatase phases.
