摘要
本文选用聚乙二醇为表面活性剂利用水热法合成了球状纳米ZnO。通过XRD与SEM对样品的物相和形貌进行表征分析。结果表明:制备出的ZnO材料为六方晶系的单质,形貌呈现为球形。在模拟太阳光下,利用ZnO对模拟废水(亚甲基蓝)进行了光催化性能研究,研究结果表明其降解效率最高可达99.2%,说明纳米ZnO具有很高的催化活性。
In this paper, the synthesis of spherical nano ZnO as surfactant was made using polyethylene glycol by hydrothermal method. Samples were investigated by X-ray diffraction （XRD）. The morphology of the samples were analyzed by scanning electron microscopy （SEM）. The result shows that： as prepared ZnO is hexagonal wurtzite. The morphology is spherical. Under the simulated sunlight, wastewater （methylene blue）with ZnO was studied in test of photocatalytic performance, Results indicates that the degradation rate is up to 99.2%,the nano- ZnO performance high catalytic activity.
