The application of NO x storage and reduction (NSR) catalysts for the cleanup of diesel engine exhaust gases requires unequivocally a structured support. In this paper, a cordierite monolithic substrate on which Al 2 O 3 was washcoated and then the active phases, namely Pt and Ba, were incorporated by adsorption from solution and impregnation, respectively, is innovatively...
Molecular and dissociative adsorption processes of methanol on isolated vanadate groups have been studied by means of density functional theory calculation at the B3LYP computing level. The catalyst is represented by an isolated vanadia unit in two environments: hydrated and supported. First, a OV(OH) 3 model considers hydrated conditions and second, a OV(OTiO 2 H) 3 cluster...
