| 摘 要： | 以Bi(NO_3)_2·5H_2O和NH_4VO_3为原料,采用微乳液法制备球型BiVO_4光催化剂。用亚甲基蓝溶液模拟有机废水,在紫外光照下,研究亚甲基蓝的光催化降解过程。利用X射线衍射和扫描电子显微镜等测试技术,对球型BiVO_4光催化剂进行表征。结果表明,乳液法制备的球型BiVO_4光催化剂具有良好的光催化性能,对亚甲基蓝的光降解率几乎可达100%。

| Abstract: | Using Bi（NO3）2 · 5H2O and NH4VO3 as the material, spherical BiVO4 photocatalyst was synthesized by microemulsion method. Degradation of methylene blue over spherical BiVO4 photocatalyst was studied using simulated methylene blue waste water and ultraviolet light. Mierostructure and catalytic properties of BiVO4 were characterized by XRD and SEM. The results indicated that BiVO4 prepared by mieroemulsion method exhibited good photoeatalytic properties, with methylene blue deeolorization rate of 100%. |
