摘要：
TiO2-reduced graphene oxide (RGO) composite are successfully prepared by UV-assisted photocatalytic reduction of graphite oxide by TiO2 nanoparticles in ethanol. These nanocomposites prepared with different ratios of graphene oxide (GO) were characterized by scanning electron microscopy, transmission electron microscopy, X-ray diffraction spectroscopy, UV-vis absorption spectrophotometer (UV-vis), and X-ray photoelectron spectroscopy. Photocatalytic degradation of nerve agent, isopropyl methylphosphonfluroride, Sarin (GB) as a real Chemical Warfare Agent on nanocomposites have been studied using Gas chromatography/mass spectrometry analysis in ambient atmosphere. RGO-TiO2 nanocomposites exhibited much higher photocatalytic activity than TiO2 for degradation of GB under visible light irradiation.
