Calcination of a Pt/Ba/CeO2 catalyst at 700 °C and subsequent reduction in hydrogen, carbon monoxide or propene at 350–550 °C resulted in a considerable improvement of its NOx storage-reduction (NSR) properties compared to those of a freshly prepared Pt/Ba/CeO2 catalyst. This behavior is traced back to the temporary formation of BaPtO3 perovskite which leads after reduction to well-distributed Pt...
The behavior of Pt during aging of Pt/Ba/CeO 2 and Pt/Ba/Al 2 O 3 NO x storage-reduction catalysts (NSR) was studied using model catalysts with high and low Pt loadings. Pt composite formation, due to the possible reaction between BaO and platinum oxides, was observed in several cases and was elucidated by a series of analytical techniques, including X-ray diffraction...
