The smaller diameter of carbon nanofiber by CO/H〓 or CH〓/H〓 than by 〓 is found due to the existence of a self-organized relationship between the active metal particle and carbon source. The graphitization degree of CNF is related to the integration and stacking mode of graphite platelet, which is determined by the interaction between active metal composition and carbon source. We find that similar-structured CNF with higher graphitization degree is produced on iron-based catalyst than that on nickel-based catalyst. Combined with the results by in-situ XRD measurement, the graphite platelet orientation is dependent on the dissociation rate of carbon source on the metal surface and the diffusion mode. There exists an induced period when carbon atoms diffuse into the bulk metal phase, thus to form fish-bone carbon nanofiber while no induced period when carbon atoms diffuse on the metal surface, thus to form tubular carbon nanofiber. Furthermore, support effect on the graphite platelet orientation is studied on the iron-based catalyst.
