摘　　要：氮掺杂可以调控碳纳米管的电子结构及表面性质,以吡啶氮、吡咯氮(N-5)、石墨氮、氧化吡啶、-NO2及-NH2等形式进行掺杂的含氮官能团可提高碳纳米管的氧还原催化活性、赝电容、润湿性能及供电子特性。文章综述氮掺杂碳纳米管的3种制备方法:同步原位掺杂、碳化含氮物质、后处理,及其在氧还原反应、超级电容器和支撑材料方面的应用,并综述了不同种类含氮官能团的作用。The electronic structure and surface character of carbon nanotube can be adjusted by nitrogen do- ping. The nitrogen groups include pyridine, pyrrole, graphitic nitrogen, oxidized pyridine, -NO2 and -NH2, etc. , which enhance the catalytic activity of oxygen reduction, pseudo-capacitance, wettability and electron-donor property of carbon nanotubes. The preparation methods of nitrogen doped carbon nanotube, including synchronous in-situ do- ping, carbonization of nitrogen-containing materials and post-treatment are summarized. The application of nitrogen doped carbon nanotube in oxygen reduction reaction （ORR）, super-capacitor and supporting materials is reviewed, as well as the role of each nitrogen group in the above mentioned fields.
