Effects of neutron irradiation at different fluencies on nanosized anatase titanium dioxide

Original language description

Nanosized anatase polymorph of titanium dioxide was irradiated at normal conditions at different fluencies. Neutron irradiation was conducted at IBR-2 high-flux pulsed reactor at fluencies of 4.0 x 10(12) n/cm(2), 8.0 x 10(12) n/cm(2), 1.3 x 1013 n/cm(2), 4.0 x 10(14) n/cm(2) and 1015 n/cm2 (neutron energy E > 0.1 MeV). X-ray diffraction, neutron diffraction analysis, Raman and FTIR spectroscopy were used to examine the crystal structure and the surface of the anatase polymorph after irradiation. X-ray and neutron diffraction analysis show deviations in the values for the unit cell volume with increasing fluence and some anneling effect for the highest fluence. Raman spectra analysis show that no phase transition occurs in the material at all irradiation fluences investigated. FTIR spectra analysis unveil that water molecules adsorbed on the material surface disintegrate under the influence of fast neutrons, converting to briged hydroxils on the surface of TiO2.
