The composite photocatalyst was characterized by X-ray diffraction(XRD), field-emission scanning electron microscopy(FESEM), high-resolution transmission electron microscopy(HRTEM), Fourier transform infrared(FT-IR) spectroscopy, UV-vis diffuse reflection spectroscopy, X-ray photoelectron spectroscopy(XPS), photoluminescence(PL) spectroscopy and BET surface area measurements.
