碘氧化铋可见光催化降解青霉素研究

Research on Catalytic Degradation of Bismuth Oxyiodide (BiOI) on Penicilin under Visible-light

在较低的温度下,采用溶剂热法合成了碘氧化铋(Bi OI)纳米片组装的微结构,研究了可见光驱动下Bi OI产品对青霉素的光催化降解性能。扫描电子显微镜(SEM)测试发现,样品呈规则的球状,尺寸均匀。X射线衍射(XRD)测试表明,产品具有良好的结晶性。另外,在可见光驱动下,Bi OI可以有效去除水中的青霉素。

The microstructure of nanoslice of Bismuth Oxyiodide（Bi OI） was synthesized by solvothermal method at lower temperature. The photocatalytic degradation performance of Bi OI on Penicillin under the visible-light-driven was studied. The scanning electron microscope（SEM） test found that the product is microspheres with uniform sizes. The product possesses good crystallinity in the X-ray diffraction（XRD）test. In addition, it was found that the Bi OI product can effectively remove Penicillin in the water under the visible-lightiven.
