摘要
利用水热法制备了BiVO4粉体,并通过X射线衍射(XRD)、扫描电镜(SEM)、紫外一可见漫反射光谱(DRS)等对催化剂进行了表征。以制备的BiVO4为催化剂,考察了可见光照射下其对亚甲基蓝的降解效果。研究结果表明对初始质量浓度为10 mg/L的亚甲基蓝溶液50 mL,BiVO4加入量为0.6 g/L,经500 W氙灯(可见光)照射6 h后,亚甲基蓝的脱色率可达64%。
The BiVO4 catalyst was prepared by hydrothermal method and was characterized by X-ray diffxaction (XRD), scanning electro microscopy (SEM), and UV-Vis diffuse reflectance spectroscopy (DRS). The photocatalytic activity of the catalyst toward degradation methylene blue (MB) was studied under visible-light irradiation. The degradation rate of MB with BiVO4 was 64 % after being treated for 6h under 500 W visible-light irradiation using 0.6 g/L BiVO4 as the photocatalyst.
