Abstract:

Article Preview

In this research, the nanometer-sized TiO2/quartz sand photocatalyst was prepared by sol-gel method. The structure of the composite samples was characterized by X-ray diffraction (XRD), scanning electron microscope (SEM) and X-ray photoelectron spectroscopy (XPS). And the photocatalytic degradation for the methylene blue (MB) solution have been inverstigated in visible light. The influence of calcining temperature was discussed. The result showed: heat treatment of the material loaded on quartz sand at 400 °C was most effective. The decolorization rate of methylene blue (MB) can be reached 96.92% under 4.5 h xenon lamp irradiation.
