在多孔的阳极的氧化铝(泛美航空公司) 的 V_2O_5 nanotube 数组模板从大音阶的第五音准备了由的 V_2 O_5 被获得融化熄灭方法。X 光检查粉末衍射和选择区域电子衍射研究证明 V_2O_5 nanotubes 是 oithorhombic。结果 bys 装电子显微检查法和传播电子显微检查法结果显示出高度订的一种一致直径形式穿的那 V_2O_5 nanotubeswith。nanotubes 的直径和长度取决于孔径和使用的 PAA 模板的厚度。sol-geltemplate 过程是一个节省费用、简单、乐意地控制的方法准备金属 oxidesnanomaterials,这被证明。由于量尺寸效果,在泛美航空公司的 V_2O_5 nanotubes 的光吸收边沿关于体积 V_2O_5 的展出重要蓝移。
V2 O5 nanotube arrays in porous atomic alumina ( PAA ) template were obtained from V2O5 sols prepared by melt quenching method. X-ray powder diffraction and selected area electron diffraction investigations demonstrate that V2O5 nanotubes are orthorhombic. Results by scanning electron mieroscopy and transmission electron microscopy results shove that V2O5 nanotubes with a uniform diameter form highly ordered arrays. The diameter and length of the nanotubes depend on the pore diameter and the thickness of the PAA template used. It is proved that the sol-gel template process is a cost-saving , simple and readily-controlled method to prepare metal oxides nanomaterials .Owing to the quantum size effect. the optical absorption edge of V2O5 nanotubes in PAA ehibits a significant blue shift with respect to that of bulk V2O5.
