摘要
以CuCl2.2H2O和NaOH为起始反应物,在没有任何表面活性剂或模板的辅助下,于80℃的水浴中恒温60 min,快速合成了树叶状的CuO微结构.利用X-射线粉末衍射仪和场发射的扫描电子显微镜对所得产物的物相和形貌进行了系统的表征,并调查了起始反应物的摩尔比、反应的温度和时间等实验参数对最终产物形貌的影响.实验显示,所得的树叶状的CuO微结构在365nm的紫外光的照射下具有强烈的促进有机小分子降解的能力.这在环境治理与防护领域有潜在的应用.
Leaf-like CuO microstructures have been successfully synthesized through a simple water bath method in the absence of any surfactant or template at 80℃ for 60 min,using CuCl2·2H2O and NaOH as the initial reactants.The asobtained product was characterized by X-ray powder diffraction（XRD） and field emission scanning electron microscopy（SEM）.Some factors influencing the morphology of the final product,such as the original molar ratio of Cu2＋/OH-,the reaction temperature and time,were investigated.Photocatalytic experiments showed that leaf-like CuO microstructures owned stronger ability to promote the degradation of safranine T under the irradiation of 365 nm UV light.
