摘　　要：乙醇催化燃烧法可以方便的制备出碳纳米管和碳纳米纤维。介绍采用该方法制备出一种独特的竹节形的碳纳米管，利用乙醇作为碳源和燃料，提供材料生长所需的能量；利用Cu薄片作为基底；利用FeCl3或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），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。实验也表明制备的竹节形碳纳米管的形貌和微结构与其独特的制备条件有关，如：火焰的抖动，催化剂先体溶液的浓度，制备时间等。并对竹节形碳纳米管的形貌和生长机制进行了详细的讨论。The ethanol catalytic combustion technique was used to synthesize carbon nanotubes and carbon nanofibers. In this paper, a novel bamboo-like carbon nanotubes was synthesized by ethanol catalytic combustion technique. The as-grown bamboo-like nanotubes was characterized by means of scanning electron microscopy, transmission electron microscopy. The results show that the carbon nanotubes have a clearly bamboo-like structure, which is affected by the unique synthesis conditions, such as concentration of catalyst precursor solution, pretreatment and sampling time, flame perturbations etc. We have depicted morphology and structure of bamboo-like nanotubes in detail, also tentatively proposed and discussed for the growth mechanism of bamboo-like carbon nanotubes.
