Preparation of C60(O) n -ZnO Nanocomposite Under Electric Furnace and Photocatalytic Degradation of Organic Dyes
Abstract:Zinc oxide (ZnO) nanoparticles were synthesized sonochemically by applying ultrasonic irradiation to a mixed aqueous-alcoholic solution of zinc nitrate with sodium hydroxide at room temperature. The morphology and optical properties of the ZnO nanoparticles were examined by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and UV-vis spectroscopy. The C60(O) n -ZnO nanoparticles were synthesized by heating a mixture of C60 and 3-chloroperoxybenzoic acid in a benzene solvent under the reflux system. The heated C60(O) n -ZnO-ZnO nanocomposite was synthesized in an electric furnace at 700°C for two hours. The heated C60(O) n -ZnO-ZnO nanocomposite was characterized by XRD, SEM, and TEM, and examined as a catalyst in the photocatalytic degradation of organic dyes by UV-vis spectroscopy. The photocatalytic effect of the heated C60(O) n -ZnO-ZnO nanocomposite was evaluated by a comparison with that of unheated C60(O) n -ZnO nanoparticles, heated C60(O) n -ZnO nanoparticles, and unheated C60(O) n -ZnO-ZnO in organic dyes, such as methylene blue (MB), methyl orange (MO), and rhodamine B (RhB) under ultraviolet light at 365 nm.
