Abstract

Sol-gel method was used to prepare carbon-doped TiO₂ nanoparticles and characterized by XPS, XRD, Photoluminescence and UV-visible spectra. UV-visible diffuse reflectance spectra showed that carbon-doped TiO₂ exhibited an improved absorption in the visible light range. The visible light photocatalytic activity of carbon-doped TiO₂ was ascribed to the presence of oxygen vacancy state between the valence band and conduction band because of the formation of Ti³⁺ species in the prepared carbon-doped TiO₂. The catalyst calcined at 500 °C showed the highest photocatalytic activity in the degradation of methylene blue under visible light irradiation. The possible mechanism was presented.
