Sažetak
Nanostructured sol-gel TiO2 films were prepared on a glass substrate by means of the dip-coating technique with titanium tetraisopropoxide as a precursor. TiO2 sols were synthesized with and without the addition of polyethylene glycol (PEG) as a structure-directing agent. The synthesized sol-gel TiO2 were characterized by XRD, AFM, FTIR and Micro-Raman spectroscopy. The photocatalytic activity of the films was evaluated by the photocatalytic degradation of Lissamine Green B (LGB) dye (dissolved in water) as a model pollutant with the predominant irradiation wavelengths of 365 nm (UV-A). It was found that the addition of PEG to the initial sol affects the surface morphology and the photocatalytic properties of prepared sol-gel TiO2 films. AFM analysis confirmed the presence of nanostructured sol-gel titania films on the glass substrate. Roughness parameters (Ra, Rq, and Zmax) of the sol-gel TiO2 film with the addition of PEG are higher than the parameters of the sol-gel TiO2 film without the addition of PEG. The TiO2 film prepared with the addition of PEG has a higher surface density (a larger active surface area) and a better photocatalytic activity in the degradation of the LGB dye solution than the TiO2 film prepared without the addition of PEG.
