Abstract
Photocatalytic and catalytic oxidation of 2-propanol (representative VOC’s compound) were compared over mixed (Au)TiO2-CeO2-based catalysts. The role of support in Au catalyzed oxidation reaction under photo and dark conditions was studied. In the photocatalytic oxidation CeO2 had a negative effect on the performance towards the alcohol conversion of both TiO2-CeO2 and Au/TiO2-CeO2 catalysts, being Au/TiO2 the most active system. On the contrary mixed TiO2-CeO2 and Au/TiO2- CeO2 samples showed a higher catalytic oxidation efficiency for 2-propanol conversion compared to the single oxides.
