Effective Visible Light-Activated B-Doped and B,N-Codoped TiO2 Photocatalysts

A simple low cost method permits controlled, reproducible doping of TiO2 anatase by boron. The resulting materials exhibit red-shifted absorption spectra and unprecedented photocatalytic activity under visible light. XP spectra are consistent with the presence of "active" and "inactive" forms of B corresponding to substitutional boron and boric oxide-like material, respectively.
