A composition that comprises a titanium compound, an iron compound, and a tungsten compound, wherein the titanium compound has a microcrystalline anatase structure and/or is obtained in the production of TiO2 according to the sulphate process, during hydrolysis of a solution which contains titanyl sulphate, and also in that the composition has a vanadium content, calculated as V, of less than 0.15 wt. % in relation to the solids content of the composition. A catalyst or catalyst raw material containing the claimed composition, as well as to a dimensionally stable and catalytically active solid body can be obtained by mixing the composition defined above with binders, plasticisers and optionally, further additives, molding the obtained composition preferably by extrusion, and subsequently carrying out calcination, or by providing a dimensionally stable and catalytically active solid body that can be obtained by applying the composition, optionally together with binders, plasticisers and further additives, to a substrate, and subsequently carrying out calcination.

Raw materials for vanadium-free or vanadium-reduced denox catalysts, and method for producing same

A composition includes titanium dioxide-containing digestion residue from titanium dioxide production, and at least one further component which is catalytically active. Dimensionally stable, catalytically active solids which are obtained from this composition can be used as catalyst, for example for minimizing nitrogen oxides.

Supported catalyst of digestion residues of titanyl sulphate-containing black solution

The invention relates to fine-particulate zirconium titanates or lead zirconium titanates and a method for production thereof by reaction of titanium dioxide particles with a zirconium compound or a lead and zirconium compound. The titanium dioxide particles have a BET surface of more than 50 m/g. The lead zirconium titanates can be used for the production of microelectronic components.
