以三聚氰胺和尿素为氮源，采用热化学气相沉积法制备了竹节状定向掺氮碳纳米管。同时，以二茂铁为催化剂和碳前驱体。由此得到的三聚氰胺NCNT(M-NCNT)在极限电流密度和转移电子数量方面表现出了优越的ORR性能。X射线光电子能谱(XPS)和拉曼光谱的进一步表征表明，与含尿素的NCNT相比，M-NCNT具有更高的氮含量和更多的缺陷，这表明氮前驱体对NCNT的氮含量和结构有重要的影响。结果表明，氮含量越高，缺陷越多，ORR性能越好。
The aligned nitrogen-doped carbon nanotubes (NCNT) with bamboo-like structure are synthesized via thermal chemical vapor deposition using melamine and urea as different nitrogen precursors. Meanwhile, ferrocene is used as catalyst and carbon precursor. The resulting NCNT with melamine (M-NCNT) have shown superior ORR performance in terms of limiting current density and number of electrons transferred. Further characterizations by X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy illustrated higher nitrogen content and more defects in M-NCNT compared to that in NCNT with urea (U-NCNT), which indicate the important role of the nitrogen precursor in nitrogen content and structure of NCNT. It is concluded that higher nitrogen content and more defects of NCNT lead to high performance of ORR.
