Abstract
A nitrous oxide (NO) removal catalyst composite is described, which includes: a NO removal catalytic material on a carrier, wherein the catalytic material comprises a platinum group metal (PGM) component on a ceria-containing support having a single phase, cubic fluorite crystal structure. The catalytic material is effective to decompose nitrous oxide (NO) to nitrogen (N) and oxygen (O) and/or to reduce NO to Nand water (HO) and/or (CO) under conditions of an exhaust stream of an internal combustion engine operating under conditions that are stoichiometric or lean with periodic rich transient excursions. Methods of making and using the same are also provided.
