摘要
以十六烷基三甲基溴化铵为模板,采用共沉淀法合成了AgBr/CeO2复合物,用TEM、XRD和XPS等对产物进行了表征。研究了AgBr/CeO2复合物对甲基橙的光催化效果,探讨了该复合物的催化持久性,以及反应时间、pH、H2O2用量等对光催化降解效果的影响。
In the presence of the CTAB soft template,AgBr/CeO2 nanocomposites were prepared by co-precipitation method.The products were characterized by TEM,XRD,XPS and UV-Vis spectra.The photocatalytic activity of the AgBr/CeO2 nanocomposites was studied by the photo-degradation of methyl orange.In addition,the effect factors,such as reaction time,solution acidity,amounts of H2O2 and the catalyst as well as repeat use of the catalyst,were discussed in detail.
