A one-dimensional model of NO oxidation and NO x storage on Pt/BaO/Al 2 O 3 monolith catalysts has been developed to predict evolution of the effluent gases as well as surface species during the storage portion of the NO x trap cycle. The model combines separate descriptions of oxidation and storage

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

The influence of the choice of platinum precursor on the catalytic performance of Pt/BaCO 3 /Al 2 O 3 NO x storage catalysts was studied. The precursors used in the preparation of the catalysts were: (i) hexachloroplatinic acid [H 2 Pt(Cl) 6 ], (ii) tetraammineplatinum hydroxide [Pt(NH 3 ) 4 (OH) 2
