C-Doped TiO₂ with Visible Light Photocatalytic Activity

Article Preview

Abstract:

Carbon doped titanium dioxide photocatalysts have been synthesized by a precipitation method. Anatase TiO2 was obtained when the precipitate was heat-treated at 400°C when rutile phase appeared at 600°C. The absorption spectra of the powders showed strong absorption in visible region. For the sample calcined at 400 °C , the absorption extended up to 750nm. X-ray photoelectron spectrum (XPS) confirmed that carbon atoms were incorporated into the TiO2 crystal lattice. Photodegradation experiments showed that the powders had visible-light degradation activity.
