摘要
分别以二乙胺和仲丁胺为碳源和氮源,以Fe/SBA-15分子筛为催化剂,经过973 K高温催化裂解,得到了含氮竹节状碳纳米管(CNX)。比较了两种不同的碳源对所合成的竹节状碳纳米管的内直径、外直径以及竹节长度的影响,并从含氮竹节状碳纳米管的生成机理上解释了产生这种现象的原因。
Bamboo-shaped,nitrogen-doped carbon nanotubes were synthesized by catalytic method with organic amine（diethylamine and butylamine） as carbon and nitrogen sources.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 different carbon sources on the inner diameter,outer diameter and the bamboo pitch length of nitrogen-doped nanotubes were discussed and the phenomenon has been explained.
