Annotation

Samples of nitrogen-doped nanocrystalline titanium dioxide were studied by electron-paramagnetic resonance technique. It was found that the doping of a material with an admixture of nitrogen leads to the appearance of nitrogen-containing paramagnetic centers, viz., N⊙ and NO⊙ radicals. The recharge effect of these centers was observed during illumination. These results may be useful for the development of photocatalytic filters based on doped nanocrystalline titanium dioxide.
