Abstract

The TiO₂-graphene (TiO₂-GR) composites have been successfully synthesized through the hydrothermal reaction. Different structures of TiO₂-GR composites were modified using graphene oxide (GO) and different titanium sources in hydrothermal conditions. The structure and properties of the photocatalysts have been characterized by field emission scanning electron microscope (FESEM), x-ray diffraction (XRD), Raman spectroscopy, Fourier transform infrared spectroscopy (FTIR), x-ray photoelectron spectroscopy (XPS), photoluminescence spectra (PL), UV–vis diffuse reflectance spectra (DRS), and Brunauer–Emmett–Teller (BET). The results showed that due to the larger interfacial contact between TiO₂ and graphene, and its greater surface area, the poriferous TiO₂-GR composite exhibited the best photocatalytic properties and adsorption performance compared with the other nanocomposites.
