  • 摘要: 采用一步水热法制备了FeVO4/BiVO4光-Fenton复合催化剂，采用X射线衍射仪（XRD）、扫描电子显微镜（SEM）、X射线光电子能谱（XPS）和紫外可见漫反射（UV-Vis）对样品进行了表征，并以氙灯为照射光源，亚甲基蓝为目标污染物，对该催化剂的催化活性进行了评价.结果表明，与纯FeVO4和纯BiVO4比较，FeVO4/BiVO4光吸收峰明显向可见光区扩展，光催化活性显著提高.同时作为类Fenton固相催化剂也显现出较高的催化活性，在氙灯照射和H2O2下，亚甲基蓝在pH 3-9范围内均可降解，在pH 3.0时，反应40 min降解率达到90%以上.
    Abstract: A novel FeVO4/BiVO4 composite photocatalyst was successfully synthesized by a facile hydrothermal method. The physical and chemical properties of as-prepared samples were characterized by X-ray diffractions (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), and UV-Vis diffused reflection spectroscopy (UV-Vis). The catalytic activity of the prepared FeVO4/BiVO4 composite photocatalyst was evaluated using methylene blue as the target pollutant. The results indicated that under visible light irradiation the photocatalytic activity of FeVO4/BiVO4 was much higher than BiVO4 or FeVO4 alone. A higher catalytic activity of the sample was also observed in the photo-Fenton-like process. More than 90% of methylene blue was degraded in the presence of 100 mg·L-1 H2O2 under the irradiation of a 500 W xenon lamp at pH 3.0.
