Synthesis of RGO/TiO2 hybrid as a high performance photocatalyst

Nonstoichiometric titania reduced graphene oxide (RGO/TiO2) hybrid was synthesized by a simple method. The as-prepared nanomaterials were characterized by a variety of techniques, including X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and surface-enhanced Raman spectroscopy (SERS). We explored whether the RGO/TiO2 hybrid could achieve a more excellent photocatalytic activity compared with the pure anatase TiO2 nanorods for degradation of industrial dyes. The results show that the new TiO2 nanocomposites can further enhance the performance of the anatase TiO2 nanorods in the photocatalysis, and it has a potential application in industrial dye wastewater treatment.
