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.
