Sažetak
In this paper silver-doped titania (TiO2) photocatalysts were synthesized in nanoparticle form by hydrothermal method. For the preparation of colloidal suspensions the following components were used: titanium isopropoxide as a precursor, 2-propanol as a solvent, acetic acid as a catalyst, sodium borohydride as a reduction agent, oleic acid as surfactant, as well as silver nitrate as a source of silver. Hydrothermal synthesis was performed in autoclave at 180 °C for 2 hours, followed by three different post-heat treatments: 60 °C for 5 hours in vacuum (sample 1), 400 °C for 1 hour in air (sample 2) and 100 °C for 2 hours in air (sample 3). The synthesized Ag-TiO2 nanopowders were characterized by XRD, FTIR and Micro-Raman spectroscopy. The photocatalytic activity of the Ag-TiO2 nanopowders was evaluated by the photocatalytic degradation of nitrofurantoin under solar-like irradiation (Osram 300 W lamp, consists of visible light and UV component) and under visible light irradiation (Wolfram lamp with an emission spectral range from 400 to 800 nm). Photocatalytic degradation of nitrofurantoin by Ag-TiO2 nanopowders were monitored by means of UV/VIS spectrophotometry and compared with commercially available TiO2 nanopowder Degussa P25 (sample 4). According to these results, all samples showed photocatalytic activity using solar-like irradiation, the best photocatalytic properties was obtained with sample P25 followed by samples 1, 3 and 2. The highest photocatalytic activity under visible light irradiation was achieved for Ag- TiO2 sample 1, commercially available sample P25 showed negligible visible light photocatalytic activity, while samples 2 and 3 showed no visible light photocatalytic activity.
