This work aims at introducing the synthesis process of carbon nanotubes (CNTs) inside nanoporous anodic alumina (NAA) templates adopting a catalyst-free chemical vapor deposition (CVD) approach under different conditions. The nanotubular structure of NAA is prepared according to tow-step anodization process. This provides a unique platform to grow CNTs with precisely controlled geometric features. The structural features, crystalline structures and chemical composition of the resulting CNTs-NAA composites were systematically characterized using Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), High Resolution Transmission Electron Microscopy (HRTEM), X-ray Diffraction (XRD), X-ray Photoelectron Spectroscopy (XPS), Energy-dispersive X-ray spectroscopy (EDX), Fourier Transform Infrared Spectroscopy (FTIR) as well as Raman spectroscopy. Preparing the CNTs according to this template technique allows us to obtain nanotubes which are open at one/both end(s) with a uniform diameter (10-200nm) along the pore length (1-100μm) without using any metal catalyst.
这项工作旨在介绍在不同条件下，采用无催化剂化学气相沉积（CVD）方法在内径为纳米的多孔阳极氧化铝（NAA）模板中合成碳纳米管（CNTs）的过程。NAA 的纳米管状结构是根据两步阳极氧化工艺制备的。这为生长具有精确控制几何特征的 CNTs 提供了独特的平台。使用扫描电子显微镜（SEM）、透射电子显微镜（TEM）、高分辨率透射电子显微镜（HRTEM）、X 射线衍射（XRD）、X 射线光电子能谱（XPS）、能谱分析（EDX）、傅里叶变换红外光谱（FTIR）和拉曼光谱系统地表征了所得 CNTs-NAA 复合材料的结构特征、晶体结构和化学组成。根据该模板技术制备 CNTs 可以使我们获得在一个/两个末端开口且沿孔长度（1-100μm）具有均匀直径（10-200nm）的纳米管，而无需使用任何金属催化剂。
