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。

Abstract: In this study, the nano-mesoporous TiO2 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 N2 adsorption-desorption, UV-vis spectroscopy, X-ray diffraction and X-ray photoelectron spectroscopy. The photocatalytic properties of the loaded TiO2 nanomaterial were studied using methyl orange as degradation compound for the model pollutant. The results showed that the nano mesoporous TiO2 loaded with AgI exhibit good photocatalytic activity, the sample has achieved the purpose of material modification.
