Mn/Ba/Al₂O₃ catalyst for NO oxidation-storage and Pt/Ba/Al₂O₃ catalyst mixed with Mn/Ba/Al₂O₃ for NO_x storage-reduction by hydrogen were investigated. The results showed that Mn/Ba/Al₂O₃ had large nitrogen oxides storage capacity (397.9 μmolg^-1) under lean bum condition.When Pt/Ba/Al₂O₃ catalyst was mixed with Mn/Ba/Al₂O₃ in equal weight proportion, the NO_x conversion increased between 250℃ and 500℃ under the dynamic lean-rich bum conditions, and the maximum NO_x conversion increased from 95.4% to 98.2%. Mn/Ba/Al₂O₃ has promoted NO_x storing in the lean stage and improved NO_xreduction efficiency in the rich stage, these might result in higher NO_x conversion over the low Pt loading content catalyst.
