Oxidation catalyst

A wall-flow filter for filtering particulate matter from a flowing exhaust gas comprises a catalyst for catalyzing both the conversion of solid carbon in the particulate matter by oxygen and the selective reduction of oxides of nitrogen in the exhaust gas with a nitrogenous reductant, which catalyst...
