首次在水热条件下在阳极氧化铝模板表面制备了垂直排列的银纳米片阵列。AAO模板的多孔表面和前驱体溶液在制备Ag纳米片的过程中可能起着关键作用。孔的边缘可以提供许多成核和生长的活性位点，然后通过Ag在AAO膜表面的自组装逐渐形成纳米片阵列。利用X射线衍射仪（XRD）和扫描电子显微镜（SEM）对产物进行了表征，并推测了纳米片的生长机理。这项工作表明，它是可能的，使有序的纳米阵列，而不溶解模板使用水热法，这种有趣的银纳米片阵列可能提供更广泛的纳米级应用。
Vertical-aligned Ag nanoflake arrays are fabricated on the surface of an anodic aluminum oxide (AAO) template under a hydrothermal condition for the first time. The porous surface of AAO templates and the precursor solution may play key roles in the process of fabricating Ag nanoflakes. The rim of pores can provide many active sites for nucleation and growth, and then nanoflake arrays gradually form through self-assembly of Ag on the surface of AAO membranes. The product is characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM), and a growth mechanism of nanoflake is deduced. This work demonstrates that it is possible to make ordered nanoarrays without dissolving templates using the hydrothermal method, and this interesting Ag nanoflake arrays may provide a wider range of nanoscale applications.
