摘要： The present invention relates to a catalyst for oxidizing ammonia, comprising: (i) platinum supported on a refractory metal oxide selected from alumina, silica, zirconia, titania, and physical mixtures or chemical combinations thereof, including atomically doped combinations, and, (ii) a second metal from one of the groups VB, VIB, VIIB, VIIIB, IB, or IIB of the periodic table supported on a zeolite. The present invention further relates to a treatment system for an exhaust stream containing NO x , the system comprising: at least one NO x abatement catalyst and an oxidation catalyst, the oxidation catalyst comprising the inventive catalyst, and to a method for treating emissions produced in the exhaust gas stream of a diesel or lean-burn vehicle, the method comprising: passing a vehicle's engine exhaust stream through said treatment system.
