Abstract: Provided herein are zoned catalysts that utilize components efficiently in that relatively short zones are provided to achieve specific functionalities to convert and/or trap one or more components in the exhaust stream. Highly controlled zoned are formed from one end of a monolithic carrier. The zones have a flat profile such that the zoned catalytic material within each passage of the substrate is at a substantially uniform distance from one end of the carrier. Methods of making and using the same are also provided.

Abstract: Provided are catalyst composites whose catalytic material is effective to substantially simultaneously oxidize carbon monoxide and hydrocarbons and reduce nitrogen oxides. The catalyst composites have a two-metal layer on a carrier, the two-metal layer comprising a rhodium component supported by a first support comprising a refractory metal oxide component or a first ceria-zirconia composite; a palladium component supported by a second support comprising a second ceria-zirconia composite; one or more of a promoter, stabilizer, or binder; wherein the amount of the total of the first and second ceria-zirconia composites in the two-metal layer is equal to or greater than the amount of the refractory metal oxide component. Methods of making and using the same are also provided.

Abstract: A lean burn engine exhaust treatment articles comprising a low temperature lean NOx trap (LT-LNT) composition and methods for their use is disclosed. A lean burn engine exhaust gas treatment system including the lean burn engine exhaust treatment articles is also disclosed. The low temperature lean NOx trap (LT-LNT) compositions can comprise a washcoat layer on a carrier substrate, the washcoat layer including a platinum group metal component impregnated on a first support material comprising at least 50% alumina. The washcoat layer may further include a low temperature NOx storage material comprising a bulk particulate reducible metal oxide. Methods of monitoring the aging state of a lean burn oxidation catalyst in a lean burn engine catalyst system are also disclosed.

Abstract: A lean NOx trap composition for the treatment of exhaust gas emissions, such as the oxidation of unburned hydrocarbons (HC), and carbon monoxide (CO), and the trapping and reduction of nitrogen oxides (NOx) is disclosed. The lean NOx trap composition can have a washcoat layer on a carrier substrate including a first support material comprising greater than 50% by weight of a reducible metal oxide; 10 to 30% by weight of alkaline earth metal supported on a second support material comprising a refractory metal oxide and 50% or less by weight of a reducible metal oxide and; and a platinum group metal component supported on at least one of the first support material and/or the second support material. A portion of the first support material may further include 0.5 % to 10% by weight of an alkaline earth metal.
