Abstract: A catalyst material, more specifically a catalyst material based on TiO2/SiO2 in particulate form having a content of metal in the form of the metal oxide or metal oxide precursor, is used in chemical catalysis, especially for removal of pollutants, such as nitrogen oxides from combustion gases.

Abstract: TiO2 pigments in the anatase modification with increased light and weather resistance have the advantages of blue tint, low hardness and abrasiveness.

Abstract: A process for the preparation of a TiO2-containing catalyst or catalyst support which is stable to high temperatures is described. In this process an aqueous Ti-containing solution having a concentration of dissolved Ti equivalent to 10 to 250 g TiO2 per liter of solution is added to a suspension of not more than 10 wt. % strength of a finely disperse inorganic support material in water, the inorganic support material having a specific surface area, measured by the BET method, of >20 m2/g and any primary particle agglomerates present having a particle size of d50<10 ?m, preferably <5 ?m, the rate of addition of the Ti-containing solution to the suspension being chosen such that an addition equivalent to 0.05 g TiO2 per m2 of support surface and hour is not exceeded, the TiO2 is precipitated on the inorganic support and the product obtained is filtered, washed and calcined.
