Abstract
Thick TiO2 films, prepared using the sol-gel method on soda lime glasses, were used for the photocatalytic oxidation of methylene blue. Several sintering temperatures and times were tested. The maximum discoloration efficiency was obtained with films sintered by 2 hours at 575 and 605°C. Films were characterized by Raman Spectroscopy (Raman), X-Ray Diffraction Spectroscopy (XRD), Scanning Electron Microscopy (SEM) and UV-Visible Spectrophotometry (UV-Vis). Additionally, the effect of number of layers was analyzed, and polyethylene glycol was added to the organic precursor to determine whether this addition has a beneficial effect on the catalyst activity. It was determined that the crystalline phase predominance of TiO2 is directly related to the photocatalytic oxidation performance. ActivTM (Pilkington) glasses were also studied for comparison with the performance of the thick films.
