  • Photoluminescence spectra of TiO2

    Open Research Data
    open access

    These data contain photoluminescence spectra of TiO2 measured at the temperature of liquid nitrogen. There is a comparison of the photoluminescence spectra of TiO2 heat treated at 400-600oC in the ambient (Ar) and reduced (H2) atmospheres. These emission spectra were recorded after TiO2 excitation with a wavelength of 290 nm

  • FTIR-TiO2 heated at 400-600oC in Ar or H2

    Open Research Data
    open access

    Data contain FTIR diffuse eflectance spectra of TiO2, which was heat-treated at 400-600oC in Ar or H2. Hydrogen reduced TiO2 revealed new bands due to the adsorption of some species on the titania oxygen vacancy sites.

  • XPS-TiO2 heated in H2

    Open Research Data
    open access

    These XPS spectra were recorded for TiO2 heat-treated at 450-600oC in H2. Surface oxygen groups were determined. Deconvolution of Ti 2p peak allowed to determine Ti3+ on the titania surface.

  • EPR of TiO2 hydrogenated at 500 and 600oC

    Open Research Data
    open access

    Data contain EPR spectra of TiO2 (anatase phase) heat treated in H2 at 500 and 600oC. Sample heated at 500oC contained 4 wt% of rutile and that at 600oC 8 wt% of rutile.
