摘要
一个垂直地排列的锐钛矿 TiO2 (A-TiO2 ) nanotube 数组被涂层制作了有一个 TiO2 先锋解决方案的一个 ZnO nanorod (NR ) 模板。在涂层以后， ZnO NR 核心有选择地在酸的环境被蚀刻形成 TiO2 nanotubes (NT ) 。在经由一个热水的方法种 ZnO NR 以后，更明确地，一个滴 TiO2 先锋答案被扔覆盖 ZnO NR，其顶以前被由静电的相互作用盖住材料的化学药品盖住，然后样品是 sintered。最后，样品沉浸于导致 ZnO NR 核心的选择蚀刻的一个酸的答案。因此，仅仅 TiO2 NT 在底层上留下了。盖住的材料有效地被用来创造一个完美的、六角形的无限制的 TiO2 NT 数组，它有趣地向可见区域扩大发作吸收。
A vertically aligned anatase TiO2 （A-TiO2） nanotube array has been fabricated by coating a ZnO nanorod （NR） template with a TiO2 precursor solution. After coating, the ZnO NR cores were selectively etched in an acidic environment to form TiO2 nanotubes （NTs）. More specifically, after growing the ZnO NRs via a hydrothermal method, one drop of the TiO2 precursor solution was cast to coat the ZnO NRs, the tops of which were previously covered with chemical capping materials by electrostatic interaction, and then the sample was sintered. Finally, the sample was immersed in an acidic solution resulting in selective etching of the ZnO NR cores. Thus, only TiO2 NTs remained on the substrate. The capping material is effectively used to create a perfect, hexagonal open-ended TiO2 NT array, which interestingly extends onset absorption towards the visible region.
