Abstract: 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 CuK? 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.

Abstract: The invention relates to a device for the, (in particular continuous), oxidation of particulates from the exhaust gases of diesel motors. Said device consists of an open-pored body as a particle filter, on whose surface an oxidation catalyst is finely dispersed. The device is characterized in that from an exhaust gas temperature as low as 150° C., the catalyst causes the oxidation of particulates attached to the filter using the residual oxygen of the exhaust gas, thus keeping the filter body continuously free of particulates during almost all the operating conditions of the motor.
