Abstract

Article history: Photocatalytic and catalytic oxidation of 2-propanol, representative of volatile organic compounds Received 8 January 2016 (VOC’s), were compared over mixed TiO –CeO -based catalysts. The effect of different amounts of CeO 2 2 2 Received in revised form 20 January 2016 and the presence of gold (1 wt%) on TiO was investigated. In the photocatalytic oxidation CeO had a 2 2 Accepted 21 January 2016 negative effect on the performance towards the alcohol conversion of both TiO –CeO and Au/TiO –CeO 2 2 2 2 Available online 29 January 2016 catalysts, being Au/TiO the most active system. On the contrary mixed TiO –CeO and Au/TiO –CeO 2 2 2 2 2 samples showed a higher catalytic oxidation efficiency for 2-propanol conversion compared to the single Keywords: oxides. In this case Au/CeO catalyst had the best performance. On the basis of characterization data (XRD, Selective oxidation Raman spectroscopy, EDX, BET Surface area determinations, H -TPR, DRIFT and DRS), it was proposed Catalytic combustion that the interaction of gold with TiO caused an enhancement of the partial photo-oxidation activity to Photocatalysis acetone due to an increase of the charge separation between the excited electron and the hole of TiO
