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

## Abstract The selective catalytic reduction rate of NO with Nβcontaining reducing agents can be enhanced considerably by converting a part of NO into NO~2~. The enhanced reaction rate is more pronounced at lower temperatures by using an equimolar mixture of NO and NO~2~. The kinetics of NO oxidat
