In this paper the mechanisms that rule the reduction by hydrogen of NO x species adsorbed at different temperatures were investigated over a model LNT Pt-Ba/Al 2 O 3 catalyst and over the corresponding Ba/Al 2 O 3 system to address the role of the noble metal component in such mechanisms. It was fo
