摘要
分别采用水热和沉淀法制备ZnO光催化剂,利用X射线粉末衍射(XRD)和扫描电镜(SEM)对其物相和外貌进行分析观测,了解表征手段所反映的材料的物质结构信息。通过降解亚甲基蓝实验比较不同制备条件下所得ZnO的光催化性能。了解催化剂制备方法对其晶相、形貌及催化性能的影响。
The ZnO photocatalysts were prepared by hydrothermal and precipitation methods, and its phase and morphology were characterized by X-ray powder diffrac- tion (XRD) and scanning electron microscopy (SEM) to understand the material stru-ctural information reflected by XRD and SEM. Experiments were carried out using methylene blue as the pollutant object to evaluate and comparae with the photocataly- tic activity of ZnO catalysts to understand the influence of preparation methods for its crystal phase, morphology and catalytic properties.
