摘要
以Zn Cl2、Na HCO3和Na Y沸石为原料,通过浸渍、焙烧等工序制备出Zn O/Na Y复合材料。用X射线粉末衍射(XRD)和扫描电镜(SEM)对制备的材料进行表征,发现20-30 nm氧化锌粒子负载在Na Y沸石表面。制备的材料具有抗大肠杆菌功能,在紫外光照射下,能将大肠杆菌完全氧化分解。
A composite,Zn O/Na Y,was prepared by impregnation of Zn Cl2,Na HCO3 solution on Na Y zeolite,along with calcination at 500 ℃. XRD and SEM were used to characterize the crystalline phase and the particle size of the formed nano-materials. Zn O nanoparticles with the size of 20-30 nm were found on the surface of the zeolite.The as-prepared materials show antibacterial activities and decompose E. coli under the ultraviolet radiation.
