Abstract
The photoeffects of trapped electrons (Ti 3+) in partially reduced TiO 2 nanoparticles were studied by in situ ESR spectroscopy. For the pure phase samples, upon illumination with an energy lower than the band gap, the Ti 3+ spectra decreased in intensity; however, the initial ESR signal was restored within 30 min in the dark at 77 K. For the TiO 2 (P-25) particles, the ESR line shape changed significantly with being constant in the integrated intensity of the signal after the restoration. It was found that the trapped electrons can transfer from the anatase phase to the rutile phase in TiO 2 (P-25) by photoexcitation.
