摘要/Abstract

摘要： 以TiO₂为载体,采用双注法合成了AgBr/TiO₂复合光催化剂.利用X射线衍射仪(XRD)、紫外可见分光光度计(UV-Vis)和扫描电子显微镜(SEM)对AgBr/TiO₂的结构、光吸收、形貌进行了表征.研究了AgBr/TiO₂在可见光下对甲基橙和丁基罗丹明B的光催化活性.结果表明,与TiO₂相比,AgBr/TiO₂的光吸收范围拓展到400—600nm波段,并且随着AgBr负载量的增加,AgBr/TiO₂的可见光吸收强度增强;当AgBr与TiO₂的摩尔比为0.25时,AgBr/TiO₂具有最大催化活性;在相同条件下,AgBr/TiO₂对丁基罗丹明B的降解效果优于甲基橙.

关键词: AgBr/TiO₂, 双注法, 可见光催化性能, 甲基橙

Abstract: AgBr/TiO₂ composite photocatalyst was prepared by double-jet method using TiO₂ as substrate. The structure,light absorption and microscopy of AgBr/TiO₂ were respectively measured by X-ray diffraction (XRD),ultraviolet visible spectroscopy (UV-Vis) and scanning electron microscopy (SEM). The photocatalytic activity of AgBr/TiO₂ for degradation of methyl orange (MO) and butyl rhodamine B (b-RhB) was studied under visible light irradiation.

Key words: AgBr/TiO₂, double-jet method, visible light photocatalytic activity, methyl orange
