摘要： 采用化学气相沉积法制备了 N 掺杂多壁纳米碳管, 并运用透射电子显微镜、N2 物理吸附、热重-差示扫描量热、程序升温氧化和 X 射线光电子能谱等手段对样品进行了表征. 结果表明, 纯化处理的纳米碳管表面 N 含量为 4.2%, 其中包括吡啶、己内酰胺、氧化吡啶、吡啶酮和吡咯等含氮官能团. 研究了各种含氮官能团燃烧的动力学行为. N 原子掺杂进入碳管的石墨结构中, 提高了表面碱性, 有可能用于催化与能源转化领域. 另外, 本文提供了一种可用于场发射器件的杯状闭合结构纳米碳合成方法.

Abstract: Nitrogen-doped multiwalled carbon nanotubes (MWCNTs) were produced by catalytic chemical vapor deposition. The surface and structural properties were investigated by transmission electron microscopy, nitrogen physisorption, thermogravimetry-differential scanning calorimetry, temperature-programmed oxidation (TPO) and X-ray photoelectron spectroscopy. The surface of the purified sample contained 4.2% nitrogen atoms and comprised pyridine, lactam, pyridine oxide, pyridone and pyrrol functional components. TPO results reveal the combustion kinetics of each nitrogen-containing functional group. The nitrogen atoms are incorporated within the graphitic structure to give a basic surface, which will play an important role in the investigation of catalysis and energy conversion. A convenient route to a closed cup-like carbon nanostructure applicable to field emission devices is also reported.
