| 摘 要： | 本文提出了一种磁控溅射和阳极氧化相结合制备Cu掺杂TiO2纳米管(Cu-TNT)阵列的方法。掺杂后的样品通过扫描电镜(SEM)、X射线衍射(XRD)、透射电镜(TEM)和X射线光电子能谱(XPS)等手段对其结构和光电性能做了研究与分析。研究结果表明：Cu以离子形态均匀地掺杂进入TiO2纳米管中,且为取代掺杂；Cu掺杂对TiO2纳米管(TNT)的生长具有抑制作用,对TNT的形貌有明显影响；Cu掺杂对TNT晶体生长取向也有明显影响,抑制锐钛矿(101)晶面的生长,使(101)晶面产生晶格畸变、晶面间距变宽并促进锐钛矿(004)晶面的择优生长。瞬态光电流响应分析表明Cu掺杂TNT有利于抑制光生电子-空穴对的复合速率,提高太阳能利用率。

| Abstract: | A prepared method of Cu-doped TiO2 nanotubes(Cu-TNT) was proposed in this paper, which combined sputtering and anodic oxidation. Scanning electron microscopy (SEM), X-ray diffraction (XRD), Transmission Electron Microscopy (TEM) and X-ray photoelectron spectroscopy (XPS) were used to study the structural and photoelectric properties of TNT. Cu-doped inhibited the growth of nanotubes, and excessive Cu-doped had a significant effect on the morphology of nanotubes. The position of Ti ion in the lattices of TiO2 nanotubes was replaced by the Cu ion., which made the (101) crystal faces a crystal lattice distortion, and the crystal plane spacings became wilder. The addition of Cu ions affected the growth orientation of the nanotubes, inhibited the growth of anatase (101) crystal plane and promoted the preferential growth of anatase (004) crystal plane. Transient photocurrent respons analysis showed that the recombination of photoelectron-hole pairs were effectively suppressed, and would improve the utilization ratio of solar light.
