摘要
以磺基水杨酸钠(SS)作为形貌调控剂,采用水热方法可控合成了各种不同形貌和维度的CuO纳米材料。结果表明,通过简单调节SS/CuCl2的摩尔比,分别合成了CuO纳米棒,纳米枝晶和海胆状球形分级结构。如果体系中不引入SS,产品则是CuO纳米片。紫外-可见光谱显示了各种CuO纳米结构与尺寸和形貌相关的吸收现象,为了探索CuO各种形貌的影响因素,我们进行了系统的实验观察。
Controllable synthesis of various CuO nanostructures has been achieved successfully via a hydrothermal route with the assistance of SS which was introduced as a shape controller. By adjusting the molar ratio of SS/CuC12 ,CuO nanorods,nanodendrites and urchin-like spheres composed of radically aligned nanorods have been prepared respectively. However,without the introduction of SS,CuO nanoplates have been obtained. UVvis spectra display size-and morphology- related absorption phenomena for various CuO nanostrctures. A systematic investigation has been carried out to understand the factors influencing the CuO morphologies.
