Abstract: 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.
