The catalytic activated diesel particle filter has a filter body and an oxidation-active catalytic coating (2) and has a selective catalytic reduction (SCR) active coating (1) in the reaction, where an ammonia storage material is contained. An arrangement maintains the layers, so that the exhaust gas to be cleaned is passed in catalytically active coating in the SCR-reaction and after that the oxidation active catalytic coating is passed. The active coating in selective catalytic reduction reaction contains multiple hydrogen cations or transition metal cations exchanged zeolites.
