Abstract

Anatase TiO₂-graphene oxide (GO) nanocomposites with different GO loadings were prepared by a solvothermal method. The prepared photocatalyst were characterized by X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infra-red spectroscopy (FTIR), and photoluminescence spectroscopy (PL). The XRD results confirmed the anatase phase of TiO₂in the composites and Raman analysis revealed the presence of GO in the nanocomposites. TEM studies indicated the uniform dispersion of TiO₂NPs on the GO surface with slight aggregation. The photocatalytic performance of the prepared nanocomposites was evaluated by the degradation of gaseous benzene under UV light irradiation. Anatase TiO₂-GO nanocomposites exhibits better photocatalytic performance than pure TiO₂nanoparticles (NPs).
