摘要
以钛酸四丁酯和NaY沸石为原料,通过浸渍、焙烧等工序制备出TiO2/NaY复合材料,经X射线粉末衍射和透射电镜表征,在NaY沸石表面上形成了尺寸均匀、粒径为4~8 nm二氧化钛粒子。在紫外光照射下,用制备的材料可以将大肠杆菌完全氧化分解。
A composite,TiO2/NaY,was prepared by impregnating NaY zeolite with tetrabutyl titanate solution and then calcinating it at 500 ℃.XRD and TEM were used to characterize the crystalline phase and the particle size of the resulting nanomaterials.TiO2 nanoparticles with the size of 4~8 nm were found on the surface of the zeolite.The prepared material is confirmed able to decompose E.coli by ultraviolet radiation.
