摘要
本实验采用水热反应法合成了形貌可控的磷酸铋纳米棒光催化剂,通过探索反应温度、时间等不同合成条件对磷酸铋形貌结构、催化性能的影响。利用X射线衍射(XRD)、扫描电镜(SEM)及紫外-可见漫反射光谱(UV-Vis)对样品的结构性能进行了表征。选取有机染料及酚类为目标降解物,在紫外光条件下考察了Bi PO4催化剂投加量、有机物初始浓度、双氧水等不同条件对光催化活性的影响;最佳催化条件下对煤化工废水中化学需氧量(COD)进行了去除并检测。
In this experiment,BiPO4nanorod photocatalyst with controlled morphology was synthesized by hydrothermal method.And the effects of different reaction conditions such as temperature and reaction time on the morphology and photocatalytic activity of BiPO4were studied.The samples were characterized by powder X-ray diffraction(XRD),electron microscopy(SEM)and Ultraviolet visible diffuse reflection(UV-Vis).In attempt to investigate the effects of dosage and initial concentration on the photocatalytic activity,organic dyes phenols were selected as the target pollutants to test the photocatalytic activity of BiPO4under UV-light irradiation.In addition,the COD of coal chemical wastewater was tested.
