摘要：

(Chemical Equation Presented) Can you see the light? Calcining a mixture of urea and TiO2 produces amino-tri-striazine derivatives covalently attached to TiO2 (see scheme). Therefore, the photocatalytic activity of this material in the visible range does not originate from surface defects or the presence of nitridic, amidic, or oxide species. This dye-sensitized titania efficiently photocatalyzes the oxidation of HCOOH to CO2 and H2O. © 2008 Wiley-VCH Verlag GmbH & Co. KGaA.
