    摘要: Described is a catalyst comprising a washcoat including copper or iron on a small pore molecular sieve material having a maximum ring size of eight tetrahedral atoms physically mixed with platinum and rhodium on a refractory metal oxide support including alumina, silica, zirconia, titania, and physical mixtures or chemical combinations thereof, including atomically doped combinations. Also described is a catalyst comprising a first washcoat zone including copper or iron on a small pore molecular sieve material having a maximum ring size of eight tetrahedral atoms, the first washcoat zone being substantially free of platinum group metal; and a second washcoat zone including copper or iron on a small pore molecular sieve material having a maximum ring size of eight tetrahedral atoms physically mixed with platinum or platinum and rhodium on a refractory metal oxide support including alumina, silica, zirconia, titania, and physical mixtures or chemical combinations thereof, including atomically doped combinations. Methods and systems for treating emissions are also described.
