Abstract TiO 2 nanotubes (NTs) immobilized on carbon fibers (CFs) were successfully prepared by a hydrothermal synthesis method based on alkali treatment of TiO 2 nanowires (NWs). The as-prepared CFs with TiO 2 -NTs (CFs/TiO 2 -NTs) were characterized with a field emission scanning electron microscope (FESEM), transmission electron microscope (TEM), energy dispersive spectrometer (EDS), X-ray photoelectron spectrometer (XPS), and X-ray diffractometer (XRD). The images on FESEM and TEM show that the entire surfaces of CFs are covered by TiO 2 -NTs with the thickness of ca. 7.4 µm. The inner and outer diameters of TiO 2 -NTs are ca. 4.6 and 8.7 nm, respectively. The analyses with EDS and XPS indicate that the main elements on the surface of CFs/TiO 2 -NTs are C, O, and Ti. According to the analysis with XRD, the transformation from titanate NTs to anatase TiO 2 -NTs was realized after annealing treatment. This work may provide a novel method for immobilizing TiO 2 -NTs on flexible non-metallic substrates.

一维TiO 2 纳米线在柔性非金属基底上水热合成TiO 2 纳米管

摘要 通过对TiO 2 纳米线（NWs）进行碱处理的水热合成方法，成功制备了固定在碳纤维（CFs）上的TiO 2 纳米管（NTs）。用场发射扫描电子显微镜 (FESEM)、透射电子显微镜 (TEM)、能谱仪 (EDS)、X 射线光电子能谱仪对制备的 TiO 2 -NTs (CFs/TiO 2 -NTs) CFs 进行表征(XPS) 和 X 射线衍射仪 (XRD)。FESEM 和TEM 图像显示CFs 的整个表面都被TiO 2 -NTs 覆盖，厚度约为。7.4 微米。TiO 2 -NTs 的内径和外径约为。分别为 4.6 和 8.7 nm。EDS和XPS分析表明CFs/TiO 2 -NTs表面的主要元素是C、O和Ti。根据XRD分析，退火处理后实现了从钛酸盐NTs到锐钛矿TiO 2 -NTs的转变。这项工作可能为将TiO 2 -NTs 固定在柔性非金属基材上提供一种新方法。
