摘要
为得到性能优异的纳米半导体材料,对氧化镍纳米结构空心球的形成机理进行了研究和探讨。以醋酸镍与氨水混合液做为前驱体进行实验,采用一步水热法和随后的热处理,得到了氧化镍纳米结构空心球,并用场发射扫描电子显微镜、X-射线衍射和透射电子显微镜等测试手段对所得样品进行了表征。结果表明:所得样品为微米尺寸氧化镍,具有规则的空心结构;氧化镍空心球的壁层由尺寸为30 nm左右的氧化镍纳米晶构成,部分纳米晶之间存在一定程度的结构有序性。另外,在研究氧化镍空心微球的形成过程中发现:NH3起到了非常重要的作用。
In order to obtain nanometer semiconductor materials with excellent properties,the formation mechanism of nickel oxide nanostructured hollow spheres was studied and discussed.Multi-layer core-shell structural NiO hollow micro spheres were synthesized by hydrothermal method and subsequent heat-treatment using Nickel acetate and ammonia as precursors,and the samples were characterized by X-ray diffraction,field emission scanning scanning electron microscopy,transmission electron microscopy.The results show that the hollow sphere samples are pure cubic NiO,and NiO hollow spheres are assembled by Nanoparticles with the size of about 30 nm.Some nanocrystals have a certain degree of structure order.In addition,it is found that NH3 plays a very important role in the formation of nickel oxide hollow microspheres.
