In this work, we have prepared TiO2 nanotubes (TNT)/reduced graphene oxide (rGO) composites by hydrothermal method for enhancing photocatalytic activities. Structural properties of the samples were characterized by X-ray diffraction spectroscopy (XRD), and scanning electronic microscopy (SEM). Photocatalytic activities were evaluated using trichloroethylene solution under solar light irradiation, and analyzed by Gas chromatography (GC). Degradation rate of TNT/rGO was improved compared to commercially available pure TNT. These results suggested that rGO has important roles for photocatalytic activity because of their reduced band gap energy and decreased recombination ratio of excited electrons. |
