采用水热法制备了不同CeO2/Bi2WO6摩尔比的CeO2/Bi2WO6复合光催化剂。X射线衍射仪(XRD)、扫描电子显微镜(SEM)和紫外可见漫反射光谱(UV-VIS DRS)技术最适合描述CeO2/Bi2WO6的光催化活性。通过在模拟太阳光照射下降解罗丹明B来评价所有样品的光催化活性。由于CeO2和Bi2WO6的引入，0.4CeO(2)/0.6Bi2WO(6)复合材料表现出最高的光催化活性，促进了电子-空穴对的分离。(C)2015爱思唯尔B.V.保留所有权利。
A straight forward strategy was designed for the preparation of novel CeO2/Bi2WO6 composite photocatalysts with differing CeO2/Bi2WO6 mole ratios by hydrothermal method. The X-ray diffraction (XRD), scanning electron microscopy (SEM), and UV-vis diffuse reflectance spectrophotometry (UV-vis DRS) techniques were found to be most suitable for describing the physicochemical properties of CeO2/Bi2WO6 onto the photocatalytic activity. Photocatalytic activities of all samples were evaluated by the degradation of rhodamine B under simulated solar light irradiation. The 0.4CeO(2)/0.6Bi(2)WO(6) composite exhibits highest photocatalytic activity due to the introduction of CeO2 and Bi2WO6, which can improve the separation of the electron-hole pairs.
