| Abstract: | Ag3PO4/NaNbO3 composite photocatalytic material was prepared by simple coprecipitation method.X-ray diffraction (XRD),X-ray photoelectron spectroscope (XPS),Scan electron microscope (SEM) and UV-Vis diffusion reflectance spectra (DRS) were employed to characterize the composition.The photocatalytic activity of Ag3 PO4/NaNbO3 was investigated by simulation of methylene blue (MB) dye pollutants under the xenon lamp (220 V,350 W) conditions.The higher photocatalytic activity of Ag3 PO4/NaNbO3 was attributed to the synergistic effects of more visible light absorption and minimum electron hole recombination.The experimental results show that the composite of Ag3PO4/ NaNbO3 catalyst with molar ratio 4 ∶ 1 exhibited the highest degradation efficiency.The degradation rate of half an hour reached to 92.4％. |
