摘要：
The potentiality of a Pt-K/Al2O3 catalyst in the simultaneous removal of particulate matter (soot) and NOx is investigated in this work by means of Temperature Programmed Oxidation (TPO) experiments and Transient Response Method (TRM), and compared with Pt-Ba/Al2O3. The results point out the higher performances of K-based sample in the soot combustion as compared to the Ba-based catalyst, and similar behaviour in the NO (x) -storage.
