Disclosure relates to a slip catalyst for reducing NO2 content in an exhaust train of an internal combustion engine flowed through by an exhaust gas flow, which has an oxidizing catalyst for the formation of NO2 and a particulate filter arranged downstream for binding carbon black particles and simultaneous and/or subsequent reaction of the same with NO2 formed on the oxidizing catalyst, having a substrate that is provided with a coating, which coating reduces a proportion of NO2 in the exhaust gas flow flowing through. The coating has at least two elements from the group of rare-earth metals, which are present in the coating in the form of a salt or an oxide or in an elementary form and in a concentration of more than 300.0 g/m3. |
