One step hydrothermal synthesis of TiO2-reduced graphene oxide sheets

Abstract

We demonstrated an environmentally friendly and efficient route for the preparation of titanium oxide (TiO₂) nanoparticles-reduced graphene oxide composite with a one-step hydrothermal method using glucose as the reducing agent. The reducing process was accompanied by generation of TiO₂ nanoparticles. The structure and composition of the nanocomposite has been characterized by Fourier transform infrared spectroscopy, Raman spectroscopy, X-ray diffraction, thermal gravimetric analysis and atomic force microscopy. The TiO₂-coated RGO nanocomposite was shown to improve the photocatalytic property of TiO₂, which would be promising for practical applications in future nanotechnology.
