Abstract A series of Pt–Ba/Al 2 O 3 NO x storage-reduction (NSR) catalysts having different Ba loadings (in the range 0–30%, w/w) have been prepared, characterized and tested in the NO x adsorption-reduction under realistic operating conditions. Accordingly, the role of the Ba loading on the storage of NO x and on their subsequent reduction has been addressed. The results indicated that the presence of Ba negatively affects both the catalyst morphological properties and the Pt dispersion in the… CONTINUE READING
