Nitrogen-doped titania nanoparticles were co-prepared by sol-gel and mechanical-alloying method. Raman spectroscopy was used to investigate the microstructure information of the nitrogen-doped titania nanoparticles. Besides, XPS, ESR and UV-vis absorption spectra were also analyzed as supplementary means. At first blue then red shift of 142 cm-1 peak was observed as the annealing temperatures increased. The possible reasons for the shift were discussed.

Nitrogen-doped titania ( TiO 2-x N y) nanoparticles with excellent visible-light-reactive photocatalytic activity were successfully prepared by a microwave-assisted hydrothermal process. The obtained TiO 2-x N y powders showed high specific surface area, fine particle size and excellent photocatalytic ability for the oxidative destruction of nitrogen monoxide under irradiation of both visible-light (λ > 510 nm) and UV light (λ > 290 nm).

Doped Titania

Nitrogen doped titania was coupled with the commercial titania nanoparticles by mechanical milling in liquid medium. When small amount of nitrogen doped titania was added into the commercial titania, higher intensity and longer lifetime of 1O2 was observed, and the photocatalytic activity was efficiently improved. The TiO2-xNy acts as the acceptor of photoinduced holes. The recombination of the electron-hole was effectively depressed by the heterogeneous electron transfer. This could be an effective way to obtain high active photocatalyst.
