摘　　要：以有机胺为碳和氮源,用催化方法合成出了含氮大管径竹节状碳纳米管.Fe/SBA-15分子筛为催化剂,有机胺经过973K高温裂解得到氮掺杂竹节状碳纳米管材料(CNX).比较了铁含量、二乙胺和六次甲基四胺原料对合成氮掺杂碳纳米管形貌和氮掺杂量的影响;合成出氮碳比(N/C原子比)为0.26的氮掺杂竹节状碳纳米管材料.Bamboo-shaped, nitrogen-doped, large-inner diameter carbon nanotubes were synthesized by catalytic method with organic amine as carbon and nitrogen source. By Fe/SBA-15 molecular sieve catalyst, nitrogen-doped bamboo-shaped carbon nanotubes （CNx） were synthesized at 973 K high cracking reaction temperature. The effects of Fe content, diethylamine and hexamethylene tetraamine source on the shape and nitrogen-doped content of CNx were discussed. Nitrogen-doped bamboo-shaped carbon nanotubes with N/C ratio of 0.26 were synthesized.
