Abstract: A TiO2-based catalyst precursor material in powder form includes TiO2 particles with the formula TiO(2-x)(OH)2x (x=0-1). The particles are coated with one or more auxiliary shaping agents and after coating and drying have a specific surface area of at least 150 m2/g. The material has a content of 1) 50-99.5% by weight of the titanium-oxygen compound with the general formula TiO(2-x)(OH)2x, wherein x=0 to 1, or mixtures thereof, wherein the crystalline phases of the titanium-oxygen compound are in the anatase form, and 2) 0.5-50% by weight of an auxiliary shaping agent or mixtures thereof, which evaporates, sublimates and/or decomposes upon heating to temperatures below the transformation temperature from anatase to rutile, wherein the % by weight are relative to the total weight of the dried catalyst precursor material.
