Highly oriented SnO(2) 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 SnO(2) nanotubes was tunable. The as-prepared nanostructures were composed of fine particles with sizes as small as 5 nm. Formation mechanism of SnO(2) 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.
高度取向的 SnO(2)纳米管和纳米线阵列通过使用阳极氧化铝 (AAO) 作为硬模板的简便一步湿化学方法选择性地制造。SnO(2)纳米管的壁厚是可调的。所制备的纳米结构由小至 5nm 的细小颗粒组成。还根据实验结果讨论了具有不同形状的 SnO(2)纳米结构阵列的形成机制。使用 X 射线粉末衍射、透射电子显微镜、能量色散 X 射线光谱、扫描电子显微镜和拉曼光谱对制备样品的结构、形态和组成特性进行了表征。
