Abstract: A catalyzed soot filter is provided wherein its inlet coating comprises an oxidation catalyst comprising platinum (Pt) and optionally palladium (Pd), and its outlet coating comprises an oxidation catalyst comprising Pd and optionally Pt. The Pt concentration in the outlet coating is lower than that in the inlet coating. The weight ratio of Pt:Pd in the outlet coating is in the range of 0:1-2:1. The inlet coating and the outlet coating are present on the wall flow substrate at a coating loading ratio in the range of 0.5-1.5, calculated as ratio of the loading of the inlet coating (in g/inch3(g/(2.54cm)3)):loading of the outlet coating (in g/inch3(g/(2.54cm)3)).
