使用阳极氧化铝 (AAO) 作为硬模板，通过便捷的一步湿化学方法选择性地制造了高度定向的 SnO2 纳米管和纳米线阵列。 SnO2 纳米管的壁厚是可调的。所制备的纳米结构由尺寸小至 5 nm 的细颗粒组成。根据实验结果还讨论了不同形状SnO2纳米结构阵列的形成机理。利用X射线粉末衍射、透射电子显微镜、能谱分析、扫描电子显微镜和拉曼光谱对所制备的样品的结构、形貌、成分性质进行了表征。
Highly oriented SnO2 nanotubes and nanowires arrays have been selectively fabricated via a convenient one-step wet-chemical approach using anodic aluminium oxide (AAO) as a hard template. Wall thickness of the SnO2 nanotubes was tunable. The as-prepared nanostructures were composed of fine particles with sizes as small as 5 nm. Formation mechanism of SnO2 nanostructure arrays with different shape is also discussed based on the experimental results. The structure, morphology, composition properties of the as-prepared samples were characterized using X-ray powder diffraction, transmission electron microscopy, energy dispersive X-ray spectrometry, scanning electron microscopy and Raman spectrum.
