Sažetak
In this study, sol-gel process was used for the preparation of Ce-TiO2 film with the following amount of cerium: 0.08 wt. %, 0.40 wt. %, 0.80%, 2.40 wt. %, 4.10 wt. % and 73.3 wt. %. For the preparation of the sol titanium isopropoxide and cerium (III) nitrate hexahydrate as a precursor, 2-propanol as a solvent, acetylacetone for complexation, distilled water for hydrolysis, and nitric acid as a catalyst were used. Ce-TiO2 sol was deposited on a borosilicate glass substrate using a flow coating method, dried at 100 °C for 60 min, and heat-treated at 450 °C for 120 min (3 °C/min). Photocatalytic degradation of the pharmaceutical ciprofloxacin (CIP) dissolved in water was investigated by means of Ce-TiO2 films irradiated with UV-A and solar-like radiation. The film’s surface morphology and roughness parameters were analyzed by atomic force microscopy (AFM). Thermogravimetric analysis and differential scanning calorimetry (DSC/TG) were used to determine weight loss and endothermic and exothermic reactions during heat treatment. X-ray diffraction (XRD) was used to determine phase composition and parameters and volumes of unit cells. Obtained results showed that Ce-TiO2 film with 0.80 wt. % Ce improves photocatalytic degradation of CIP under UV-A and solar-like radiation compared to the pure TiO2 film.
