摘要
通过控制温度、时间和溶液pH等实验参数,以铋盐为原料,经溶剂热反应得到了不同粒径的氯氧化铋(BiOCl)纳米片晶体,利用X-射线粉末衍射仪(XRD)和扫描电子显微镜(SEM)对所制备材料进行了表征。同时以罗丹明B为模拟污染物探究了BiOCl的可见光光催化性能。结果表明:BiOCl纳米片能够通过溶剂热的方法实现可控制备,具有较理想的可见光光催化性能,能在240min内将罗丹明B完全降解。
Abstract
By controlling the experimental parameters such as temperature,time,solution pH,and the concentration of bismuth salt used as raw material,bismuth oxychloride (BiOCl) nanometer materials with different sizes were prepared via the solvothermal reaction.X-ray powder diffraction (XRD) and scanning electron microscope (SEM) technology were used to characterize the obtained materials.In addition,rhodamine B was used as the model pollutant to testify the photocatalytic performance of BiOCl nanoplates under visible light (λ>420 nm).Research results showed that BiOCl nanoplates can be achieved through solvothermal method to realize controllable preparation,and had good visible light catalytic performance.Rhodamine B was completely degraded in a relatively short period of time.
