| 摘要: 采用一种简单的无模板水热合成法制备了具有分级结构的钨酸铋纳米花，并将钨酸铋纳米花材料应用于可见光催化去除水中的四环素类抗生素。通过X射线粉末衍射、扫描电镜、透射电镜、紫外固体漫反射、比表面分析等一系列物理表征对光催化剂和催化反应体系进行了表征。研究结果表明钨酸铋纳米光催化剂对四环素类抗生素（四环素和土霉素）均具有良好的降解能力。此外，催化剂对碱性溶液中四环素的降解效率普遍较高，且该催化剂表现出良好的循环稳定性。 | |

| Abstract: Hierarchically structured flower-like Bi2WO6 was fabricated via a simple template-free hydrothermal method. The as-prepared Bi2WO6 was applied in the removal of tetracycline antibiotics presented in aqueous phases under visible irradiation. The photocatalyst were characterized by a series of physical characterizations including powder X-ray diffraction, scanning electron microscopy, transmission electron microscopy, UV-Vis diffuse reflectance spectra, nitrogen adsorption desorption test etc. The Bi2WO6 photocatalysts showed excellent degradation capacity towards tetracycline antibiotics (tetracycline (TC) and oxytetracycline (OTC)). Moreover, the TC degradation rates were generally higher in relatively alkaline solutions. The Bi2WO6 photocatalysts exhibited excellent stability and could be recycled for reuse. | |
