摘要： The application provides articles, systems, and methods for adsorbing and desorbing nitrogen oxides (NOx) at desired temperatures. The catalytic article comprises a NOx adsorber composition comprising a platinum group metal (PGM) component disposed on or impregnated in a support material, and a substrate, wherein the catalytic article further comprises a magnetic material capable of inductive heating in response to an applied alternating electromagnetic field. The catalytic article further comprises a conductor associated therewith for receiving current and generating an alternating electromagnetic field in response thereto, wherein the conductor is positioned such that the generated alternating electromagnetic field is applied to at least a portion of the magnetic material. This field can inductively heat the magnetic material to heat the NOx adsorber composition to desorb the NOx from the NOx adsorber composition.

摘要： A filter incorporates a catalyst for the Selective Catalytic Reduction (SCR) of NOx gases and removal of particulate matter from the exhaust gas of a lean burn combustion engine, wherein the catalyst includes a vanadate component having an alkaline earth metal, a transition metal, a rare earth metal, or combinations thereof. The vanadate component may be iron vanadate. The filter includes a supported vanadate component disposed on a wall-flow filter. The method of making the filter includes applying an aqueous mixture of the supported vanadate component as a washcoat on the wall-flow filter or extruding a composition containing the supported vanadate component. The method of treating exhaust gases from an engine includes contacting the exhaust gas with the catalyst including the vanadate component.
