| Abstract: | Two types of reaction mechanism were found to proceed in the photocatalytic reaction between various alcohols and water over Pt/TiO2: the reaction of physisorbed alcohol with a hole and with the ?O11 produced by the hole from H2O. The selectivity of these reactions depends strongly on the electron donor level of the absorbed alcohol species compared with that of H2O. |
