【摘要】 以Bi（NO₃）₂·5H₂O和NH₄VO₃为原料,采用微乳液法制备球型BiVO₄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BiVO₄光催化剂进行表征。结果表明,乳液法制备的球型BiVO₄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%。更多还原

【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. Microstrueture and catalytic properties of BiVO₄ were characterized by XRD and SEM. The results indicated that BiVO₄ prepared by microemulsion method exhibited good photocatalytic properties, with methylene blue decolorization rate of 100%.更多还原
