Controlling the selectivity to N₂O over Pt/Ba/Al₂O₃ NOX storage/reduction catalysts

N₂O formation during the reduction process over NSR catalysts is analysed in this paper. The effect of catalyst characteristics and different operation parameters (chemical nature of the reductant, temperature and cycle timing) are addressed and discussed in terms of N₂O selectivity.
