Propene is among the most investigated probe molecules in the field of VOC catalytic oxidation, because of its high photochemical ozone creativity potential (POCP) [1]. Supported noble metals (Pt, Pd, Au) show high activity for VOC oxidation, although their use is limited because of the high price and deactivation due to sintering of the active phase and poisoning effects [2]. It is well-known that the support nature plays an important role in improving the activity and durability of supported noble metals. For Pd supported catalysts the oxidation activity strongly depends on the acid-base properties of the support [3,4] as well as on the metal-support interaction [5]. In the present study, the catalytic oxidation of propene was investigated over Pd catalysts supported over CeO2, TiO2, Al2O3 and M/Al2O3 oxides (M=Ce, Ti, Fe, Mn). The propene oxidation activity of a conventional Pt/Al2O3, as reference, was also reported.
