| 摘 要： | 通过水热法制备稀土Pr掺杂Bi2WO6三维花状微球，利用XRD、SEM、N2吸附-脱附、紫外-可见吸收光谱和光致发光光谱对所制备的光催化材料进行表征。通过降解亚甲基蓝评价样品的光催化活性。结果表明，1.0% Pr-Bi2WO6样品的可见光催化活性最佳，降解率达到95%。Pr掺杂提高了催化剂的可见光吸收性能并且能够束缚光生电子使得电子空穴对有效分离从而获得强氧化物质。对其光催化降解做出了合理的解释。

| 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. |
