| Abstract: The rare-earth Pr doped Bi2WO6 three-dimensional flower microspheres were synthesized by hydrothermal method. The prepared sample was investigated by X-ray diffraction, scanning electron microscopy, nitrogen adsorption-desorption, UV-Vis absorption spectroscopy and photoluminescence spectroscopy. The photocatalytic activity was evaluated by degrading of methylene blue. The results show that the 1.0% Pr-Bi2WO6 exhibits an enhanced visible light-induced photoactivity with the degradation rate of 95%. The Pr doping favors the absorption of visible light and trapping of electrons, thus the separation of electron-hole pairs is implemented effectivly and achieved strong oxidative species. This work provided a new photocatalyst with high-performance and a reasonable explanation of photocatalytic degradation. |
