N-doped TiO2 was synthesized by sol–gel method from precursor solutions with or without urea and post calcination in NH3 gas. Localized states associated with N were successfully found at 0.24 eV to 0.34 eV above valence band maximum in the band gap.

The unique characteristics of the (W, N) dopant pair is that it reduces the band gap of NaNbO3 mainly by elevation of valence band maxima, which is very much crucial for photocatalyst for hydrogen evolution through water splitting.
