摘要
研究了AgI负载纳米介孔TiO2的制备及其光降解性能.以钛酸丁酯为钛源,P123为模板剂,采用软膜板法制备了AgI负载型纳米介孔TiO2.利用N2吸附-脱附实验、紫外-可见光谱、X-射线衍射、X射线光电子能谱分析等技术对材料进行了结构表征.通过以甲基橙溶液为模拟污染物,用所得样品进行光降解实验.结果表明:TiO2负载了AgI之后光降解性能有明显的提升,达到了材料改性的目的.
In this study,the nano-mesoporous TiO 2 loaded with silver iodide(AgI)was prepared through soft template method by using tetrabutyl titanate(TBOT)as the titanium source and P123 as the template.The prepared materials were characterized by the N 2 adsorption-desorption,UV-vis spectroscopy,X-ray diffraction and X-ray photoelectron spectroscopy.The photocatalytic properties of the loaded TiO 2 nanomaterial were studied using methyl orange as degradation compound for the model pollutant.The results showed that the nano mesoporous TiO 2 loaded with AgI exhibit good photocatalytic activity,the sample has achieved the purpose of material modification.
