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
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
