Sažetak
Titanate nanotubes/titania gel blends were prepared as composite sol-gel material, deposited on a glass substrate using a doctor blade and calcined in order to create thin films. In order to get an insight in titania nanotubes’ ability to reinforce thin films, drying control chemical agents were not used. The effects of titanate nanotubes to titanium n-butoxide ratio on surface morphology, phase composition, mechanical stability and photocatalytic activity were studied. Characterization of the thin films was carried out by means of optical and scanning electron microscopy, powder X-ray diffraction, synchrotron radiation grazing incidence X-ray diffraction and mechanical stability testing. Photocatalytic properties of the obtained thin films were evaluated on the basis of methylene blue degradation. Moderate blends exhibit favourable microstructural features while the dye degradation rate was greater for films with a greater amount of titanate nanotubes.
