The adsorption and photodecomposition of ethanol that was employed as a model substrate of organic pollutants were investigated in the presence of adsorbed water with TiO 2 by solid-state 1 H NMR spectroscopy in order to obtain information about the actual photocatalytic reaction sites of organic pollutants on TiO 2 photocatalysts. Consequently it was revealed that ethanol molecules in practical conditions as contaminants were firmly captured in mobile physisorbed water layers to be photodecomposed to CO 2 and water after photoillumination, suggesting that actual photocatalytic reactions should proceed in physisorbed water layers.
