结合空间分辨电子能量损失光谱（EELS）和高分辨近边x射线吸收精细结构（NEXAFS）光谱研究了多壁碳纳米管（N-MWNT）的氮掺杂。EELS表明，大多数管是氮掺杂的。NEXAFS光谱显示类吡啶和腈N结构。高分辨率NEXAFS实验表明，氮的主要浓度来源于大量的N2分子被封装在少量的管中。
Combined spatially resolved electron-energy loss spectroscopy (EELS) and high resolution near-edge X-ray absorption fine structure (NEXAFS) spectroscopy have been used to investigate the nitrogen doping of multi-walled carbon nanotubes (N-MWNT). EELS indicates that most of the tubes are nitrogen-doped. NEXAFS spectroscopy reveals pyridine-like and nitrile N structures. High resolution NEXAFS experiments show that the main nitrogen concentration originates from a high amount of molecular N2 encapsulated into only a small quantity of tubes.
