以P₁₂₃为模板制备介孔二氧化钛（m-TiO₂），借助光还原法制备m-TiO₂-Ag复合材料。利用透射电镜（TEM）、X射线衍射仪（XRD）、傅里叶变换红外光谱（FT-IR）等对m-TiO₂-Ag复合材料进行表征。以甲基橙（MO）和罗丹明B （RhB）为脱色降解模型，测定质量分数不同的载Ag样品在可见光下光催化性能。利用生长曲线和抑菌环检测其抗菌性能。结果表明，纳米银掺杂可以显著提高介孔二氧化钛（m-TiO₂）在可见光下催化降解染料的性能，并对测试菌展现出良好的抗菌性。

Mesoporous titanium dioxide (m-TiO₂) is prepared by using P₁₂₃ as template and then high efficient m-TiO₂-Ag nano-composites are prepared via photoreduction method.The samples are characterized by transmission electron microscopy (TEM),X-ray powder diffraction (XRD) and Fourier transform-infrared spectroscopy (FT-IR).The photocatalytic performances of samples with different Ag contents are evaluated by degradation test of methyl orange and rhodamine under visible light.Their antibacterial properties are characterized by growth curves and inhibition rings.The results show that the modification by silver nanoparticles can improve effectively the performance of m-TiO₂ in photocatalytic degradation of dyestuffs and can make m-TiO₂ to exhibit excellent antibacterial properties against test bacteria.
