摘要
采用水热法、原位沉淀法合成了不同Br-和Cl-质量比的Ag_(3)PO_(4)/BiOBr/BiOCl复合光催化材料,并通过X射线衍射仪、紫外-可见分光光度计分别测试了复合材料的物相组成和光催化活性。结果表明,BiOCl会抑制BiOBr晶粒的长大,随着BiOCl复合量增加,当Br-和Cl-质量比达到1∶4时,BiOCl结晶明显完整。适量复合BiOCl能够提高Ag_(3)PO_(4)/BiOBr的光催化性能,以Br-和Cl-质量比为1∶1.5的样品最佳,可见光下催化180 min对盐酸左氧氟沙星的降解率高达88%。
The Ag_(3)PO_(4)/BiOBr/BiOCl composite photocatalytic material with different mass ratios of Br-and Cl-is synthesized by hydrothermal and in situ precipitation method,and the phase composition and photocatalytic activity of the composite are tested by X-ray diffrtometer and UV-visible spectrophotometer.The results show that BiOCl can inhibit the growth of BiOBr grains.With the increase of BiOCl compound amount,when the mass ratios of Br-and Cl-reaches 1∶4,the BiOCl crystallization is obviously intact.The appropriate amount of composite BiOCl can improve the photocatalytic performance of Ag_(3)PO_(4)/BiOBr,the sample with mass ratios of Br-and Cl-reaches 1∶1.5 is the best,and the degradation rate of levofloxacin hydrochloride is up to 88%under visible light for 180 min.
