dc.description.abstract | This paper reports an 'in situ' precipitation-reduction reaction for the scalable production of nanoscale TiO2-anchored reduced graphene oxide (RGO-TiO2) nanocomposites. RGO-TiO2 nanocomposites with different weight ratios were prepared by the simultaneous hydrolysis of titanium tetraisopropoxide (TTIP) and the chemical reduction of graphene oxide. The as-prepared samples were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, transmission electron microscopy, Ultraviolet-Visible diffused reflectance spectroscopy, and photoluminescence. The most commonly used cytostatic (antineoplastic) drug in cancer therapies [5-fluorouracil (5-FU)] was used as a model pollutant. To examine the effects of RGO, the photocatalytic degradation of 5-FU was examined by varying the operational parameters, such as catalyst amounts, solution pH, effect of scavenger, and TiO2 mass contents. Under the optimal experimental conditions, 97% of the 5-FU present was photodegraded over RGO-TiO2 (RGO-T2) within 90 min under UV light. The RGO-TiO2 composites (RGO-T2) exhibited two times higher photocatalytic activity than that of pure TiO2. The improved photocatalytic activities of the RGO-TiO2 nanocomposites were attributed to the homogeneous distribution of TiO2 nanoparticles over the surface of the RGO nanosheet, enhancement of the light absorption intensity, and suppressed recombination of photoinduced electron-hole pairs. | - |
