纳米材料是指在三维空间中至少有一维处于纳米尺寸范围或由它们作为基本单元构成的材料。一维纳米材料是指直径在1-100nm之间，而轴向长度可以达到微米量级的线性纳米材料，如纳米线、纳米管、纳米棒以及近年来大量报道的纳米带等。 由于一维纳米体系适合于研究光、电、场在一维方向上的性质，以及尺寸缩小所带来的机械性能的变化，它们是纳米尺寸的电子器件、光电子器件、机械传动装置的优良候选材料。 本文介绍了在酸性溶液中制备氧化铝纳米模板，并通过用酸和碱性溶液对模板进行腐蚀。从而在适当参数下生成纳米线，并用扫描电子显微镜（SEM）对模板和纳米线的形貌和结构进行了表征。

Nanomaterials refer to the three-dimensional Materials that at least one dimension in the nanometer size or, materials that basic units are constituted nanomaterials. One dimensional nanomaterials refers to materials have diameter of l-100nm and the axial length can be reached micron linear nanomaterials, such as nanowires, nanotubes, Nanorods and recent reports of a large number of nano-Belt. As one dimensional nanomaterials system suitable for research in optical, electrical and field in the one dimension and their small size changes the mechanical properties, this makes them excellent candidate materials for nano-sized electronic, optoelectronics and mechanical transmission device. This paper presents the acidic solution prepared nano alumina template. Through the use of acid and alkaline solution template was corroded and by appropriate parameters the nanowires were successfully generated. Scanning electron microscopy (SEM) used to characterize template an d nanowires.
