Abstract. The influence of the preparation procedure on the performance of NOx storage and reduction catalysts was investigated by means of flow reactor experiments. Three catalysts were examined; one Pt/Al and two Pt/Ba/Al samples. One of the Pt/Ba/Al samples was prepared with Pt impregnated on Al/Ba and one with Ba impregnated on Al/Pt. The results clearly show that the preparation proced…
