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。
ZnO photocatalyst was prepared by hydrothermal method and precipitation method respectively. The phase and appearance of ZnO photocatalyst were observed and analyzed by X-ray powder diffraction (XRD) and scanning electron microscopy (SEM), and the material structure information of the material reflected by the characterization means was obtained. The photocatalytic properties of ZnO obtained under different preparation conditions were compared by degradation of methylene blue. Understand the influence of catalyst preparation method on its crystal phase, morphology and catalytic performance.
