    摘要： Catalysts and catalytic articles for treating exhaust gas streams are described. In one or more embodiments, a catalyst system includes a first zone to abate nitrogen oxides by selective catalytic reduction, a second zone to oxidize ammonia and a third zone to oxidize carbon monoxide and hydrocarbons. Methods for treating the exhaust gas stream are also provided. Methods of making and using such catalysts and catalytic articles are also described.

    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.
