The Nature of Nitrogen‐Modified Titanium Dioxide Photocatalysts Active in Visible Light

Abstract

Can you see the light? Calcining a mixture of urea and TiO2 produces amino-tri-s-triazine 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. Detailed facts of importance to specialist readers are published as ”Supporting Information”.
