本文介绍了一种以各种预合成的氧化锌纳米棒阵列为牺牲模板，两步法制备定向二氧化锡纳米管阵列的有效方法。利用X射线衍射仪、扫描电子显微镜和透射电子显微镜对合成的SnO2纳米管阵列的组成和结构进行了详细的分析。由于SnO2壁与氧化锌模板之间存在一种特殊的外延关系，构建SnO2纳米管的壁具有高度的取向度，并且几乎是单晶的。我们的研究为研究这种具有近单晶性质的定向SnO2纳米管的相关物理化学性质和潜在的应用提供了机会。
In this paper, we describe an effective two-step method for fabricating aligned SnO2nanotube arrays by using various pre-synthesized ZnO nanorod arrays as sacrificial templates. The composition and structure of as-synthesized SnO2nanotube arrays were analyzed in detail by X-ray diffraction, scanning electron microscopy, and transmission electron microscopy. Because there is a special epitaxial relation between the SnO2 walls and ZnO templates, the walls building the SnO2nanotubes are highly orientated and nearly single-crystalline. Our present study provides an opportunity to investigate related physical and chemical properties and potential applications of such aligned SnO2nanotubes with nearly single-crystalline nature.
