摘要：
A catalyst composition comprising—a support comprising TiO2,—a composite oxide containing vanadium and antimony, which has a rutile-type structure different from VSbO 4 and V0.92Sb0.92O4 as determined by X-ray diffraction (XRD) analysis with CuKα radiation, and—optionally, one or more selected from the group consisting of oxides of silicon, oxides of vanadium and oxides of antimony, for selective catalytic reduction of nitrogen oxides; to a process for preparing the catalyst composition, to the catalyst composition obtained/obtainable by the process and to use of the same for selective catalytic reduction of nitrogen oxides.
