Abstract

An electron paramagnetic resonance study of nitrogen-doped TiO ₂ samples has been carried out in the dark and under illumination with light at different wavelengths. N ^· and NO ^· paramagnetic species were detected in the samples and their dynamics under illumination of TiO ₂ was investigated. Photosensitivity of the nitrogen-doped TiO ₂ and its photocatalytic activity under visible-light irradiation increases through the creation of additional levels in the band gap of TiO ₂ caused by doping.
