Carbon Nanotubes with Special Structure from the Pyrolysis Flame

Abstract:

Carbon nanotube is the one-dimensional carbon nano-materials. The synthesis of carbon nanotubes from pyrolysis flame is a new method. Variety of carbon nanotubes with special structure can be seen from pyrolysis flame due to the influence of key factors such as the concentration of reactants and catalyst particle size. The morphology and structural of carbon nanotubes were characterized by scanning electron microscope and transmission electron microscopy respectively. Carbon nanotubes with special structure such as bamboo-like, pod-like and coil-like can be seen in the experiment. The bamboo-like carbon nanotube has a bamboo-like structure clearly. The shape of pod-like carbon nanotube is very similar with the peasecod. The coil-like carbon nanotube is similar to carbon nanofiber in structure. It was discussed and analyzed that the formation mechanism of bamboo-like, pod-like and coil-like carbon nanotubes from the V-type pyrolysis flame.
