The of g-C3N4/TiO2 nanotubes were prepared using the sonochemical synthesis and hydrothermal method. The as-prepared composite photocatalysts were characterized by X-ray diffraction (XRD), Raman, scanning electron microscopy (SEM), high resolution transmission electron microscopy (HRTEM), X-ray photoelectron spectroscopy (XPS) and UV-vis diffuse reflectance spectra (UV-vis DRS). Photocatalytic activities were measured using rhodamine B solution under simulated solar light irradiation. Photodecomposition rate of g-C3N4/TiO2 nanotubes were improved compared to pure TiO2. The results indicated that reduced Pt-loaded g-C3N4 band gap energy and decreased recombination ratio of excited electrons. |
