| 摘 要： | 采用水热法,无需添加剂,在180℃通过调控pH值制备了不同结构和形貌的BiVO4可见光催化剂。利用XRD、SEM等手段对样品进行表征。结果表明,水热反应液pH值对BiVO4的晶相与形貌均有很大影响,pH为4时制备的片状BiVO4对亚甲基蓝的降解率最高（4h达91.79%）。 |

| Abstract: | BiVO4 visible-light photocatalysts with different structures and morphologies were prepared by hydrothermal method at 180℃,without the presence of any additives.The as-prepared samples were charactered by XRD,SEM.The results indicated that the pH value of reaction solution had significant impact on the crystal structures and morphologies.The highest photocatalytic degradation of methylene blue was 91.79% in 4h at pH=4 which showed that monoclinic BiVO4 exhibited the best photocatalytic activity. |
