| Abstract: | Sepiolite surpported nano TiO2 composite photocatalysts were prepared by electrostatic self-assembly method(ESAM) with titanium tetrachloride as Ti-precursor.X-ray diffraction(XRD),infrared spectroscopy(IR) and scanning electronic microscope(SEM) were employed to characterize the crystal structure and morphology of the prepared samples.The photocatalytic activity of the samples was evaluated by the degradation of methyl orange(MO) in water solution under ultraviolet light irradiation.The effects of the calc... |
