The current thesis aims at exploring the impact of structural (CeO2, La2O3) and surface (K) promoters on the solid state properties and the surface chemistry of Al2O3-based noble metal (Pt, Pd, Ir) catalysts, during nitro-gen (NOx) and/or nitrous (N2O) oxides abatement. Various characterization techniques, such as N2 physisorp-tion (BET method), X-ray diffraction (XRD), Temperature programmed methods (TPR/TPD), microscopy meth-ods (HRTEM, STEM) and infrared spectroscopy (FTIR, DRIFTS) were employed to gain insight into the impact of structural/surface promoters on the physicochemical characteristics, as well as on the activity and stability performance of the as-prepared catalysts. In any case, particular emphasis was devoted in the present thesis on the underlying mechanism of promoters and the establishment of structure-property relationships.
