Regeneration of a Pt/BaO/Al 2 O 3 NO x storage-reduction catalyst was studied using H 2 as a model reductant. We propose that the regeneration process involves a localized reaction front of the reductant that travels through the catalyst bed with complete regeneration of the trapping sites. When NH
