An anatase titanium dioxide includes at least one compound selected from oxides of Si, Al, and Zr in an amount of 2-50% b.w., calculated as oxides, of a total weight of the oxides, and a sulfur content of less than 150 ppm based on the total weight of the oxides.

Process for reducing the sulphur content of anatase titania and the so-obtained product

A process is described for the production of a catalyst preparation, in which the catalyst containing at least one inorganic compound which is solid under standard conditions is comminuted by means of a dispersion unit into particles having a maximum average particle size dof 2 &#x3bc;m, preferably a maximum of 1 &#x3bc;m, implemented in accordance with DIN 66141 and DIN 66144, and is distributed at a concentration of from 1 to 50 wt. % (relative to the finished catalyst preparation) in a liquid.
