Abstract
NOabatement compositions include cobalt oxide (CoO) doped with cerium, and have an overall formula CoCeO, with cerium occupying tetrahedral and/or octahedral sites in the spinel structure. The NOabatement compositions possess NOstorage and NOdirect decomposition activity. Dual stage NOabatement devices include an upstream portion having the NOabatement composition to adsorb and store NOat low temperature, and then release the NOat higher temperature to a downstream catalytic conversion portion.
