Improvement in the photocatalytic activity of TiO2 by the partial oxidation of the C impurities

Photocatalytic conversion of gaseous ethylbenzene on lanthanum-doped titanium dioxide nanotubes

“…A detailed quantitative process of the by-products and CO 2 will carried out in the further study. Surface hydroxyl groups, which could influence the process either by directly participating in the reaction mechanism or by affecting the adsorption of reactant molecules, were restored by reactions involving adsorbed oxygen and water molecules [53,54].…”

Vapor phase condensation of methyl acetate with formaldehyde to preparing methyl acrylate over cesium supported SBA-15 catalyst

“…Cs-O-Si, similar to the Si-O-M species [37][38][39][40], the bind energy 226 near 533 eV was due to Si-O (Si-O-Si, Si-O-H) from SiO 2 support 227 [41]. …”

A Kinetic Study of Photocatalytic Degradation of Phenol over Titania–Silica Mixed Oxide Materials under UV Illumination

“…Then the broad bands between 530 and 532 eV were de-convoluted to three additional peaks. The Ti-O-Si species was quantified using Gaussian/Lorentzian shape GL (30:70) curves with equivalent electron volts (eV) at the fullwidth-half-maximum (fwhm) by considering the band near 531.7 eV [40,42,43]. Figure 7 shows the de-convoluted O 1S spectra of all TiO 2 -SiO 2 materials prepared with different Ti:Si ratios and the calculated percentage of all the species, such as Ti-O-Si, Ti-O-Ti, Si-O-Si, Ti-O-H, and Si-O-H, which are listed in Table S1 in the supplementary section.…”
