摘　　要：采用乙醇催化燃烧法制备竹节形碳纳米管,利用乙醇作为碳源和燃料提供材料生长所需的能量,以Cu薄片作为基底,FeCl3与Fe(NO3)3作为催化剂先体。通过扫描电子显微镜(SEM)、透射电子显微镜(TEM)、喇曼光谱对黑色絮状的沉积产物进行表征。实验结果表明,产物中的碳纳米管具有较好的竹节形结构,竹节形碳纳米管的形貌和微结构与独特的制备条件有关。并对竹节形碳纳米管的生成机理进行了初步探讨。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 or iron nitrate as catalyst precursor. The as-grown black powder was characterized by means of scanning electron microscopy （SEM）, transmission electron microscopy （TEM） and Raman spectroscopy. The results show that the carbon nanotubes have a clearly bamboo-like structure, which is affected by the unique synthesis conditions. The growth mechanism of bamboo-like CNTs tentatively was proposed and discussed.
