摘要: 建立了一种制备氧化铈纳米管的新方法, 即以碳纳米管(CNTs)为模板, 在常温常压下采用液相沉积法在CNTs表面包覆CeO2, 通过煅烧除去CNTs模板, 得到氧化铈纳米管. 通过透射电子显微镜(TEM)、X射线衍射(XRD)和X射线光电子能谱(XPS)对其形貌和结构进行了表征. 所得CeO2纳米管为面心立方结构, 直径40~60 nm, 长度0.5~2 μm.

关键词: 碳纳米管, CeO2, 模板

Abstract: A facile and novel method for synthesizing cerium oxide nanotubes is reported in this paper. Carbon nanotubes(CNTs) were firstly uniformly coated with CeO2 nanoparticles by a liquid deposition approach at room temperature and normal pressure and then CNT templates were removed by calcination at a suitable temperature. The characteristics of cerium oxide nanotubes were characterized by TEM, XRD and XPS. The results reveal that the face-centered cubic-phase CeO2 nanotubes with an average diameter of 40—60 nm and a length of 0.5—2 μm is synthesized.

Key words: Carbon nanotubes, CeO2, Template
