摘　　要：本文采用乙醇催化燃烧法制备竹节形碳纳米管,此方法利用乙醇作为碳源和燃料,提供材料生长所需的能量;利用Cu薄片作为基底;利用FeCl3作为催化剂先体。黑色絮状的沉积物经扫描电子显微镜,透射电子显微镜,拉曼光谱进行表征,发现产物中较细的碳纳米管具有相对较好的竹节形结构,它的隔层是很规则的;然而较粗的碳纳米管的竹节形结构是无规则的,这与催化剂先体的浓度有关。Bamboo-like carbon nanotubes were synthesized by ethanol catalytic combustion （ECC） technique with combustion method. Copper plate was employed as substrate, ethanol as carbon source, and iron chloride as catalyst precursor. The as-grown black powder was characterized by means of scanning electron microscopy, transmission electron microscopy and Raman spectroscopy. The results show that the thinner bamboo --like carbon nanotubes have a relatively good structure that the compartment layers are more regular, while the thicker carbon nanotubes have a relatively irregular bamboo-like structure,it is affected by the concentration of catalyst precursor solution.
