摘要：

Gas-phase ethanol photocatalytic oxidation on the series of TiO2 samples has been studied by the FTIR in situ method. The TiO2 samples were prepared by the usual method and they possessed similar physicochemical properties (porosity, specific area), but were found to have different photocatalytic activities. The acidity and concentration of the Lewis centers have been measured. The TiO2 photocatalytic activity has been found to correlate with the surface acidity, and the Ti3+ and carbonate surface concentrations. (C) 2000 Elsevier Science B.V. All rights reserved.
