The Influence of Catalyst Nature on the Morphology of Multi-Directionally Grown Carbon Nanofibers

The multi-directional grown carbon nanofibers have been synthesized by catalytic combustion technique. Transmission electron microscopy and selected area electron X-ray diffraction were combined to characterize the carbon products and their catalyst, which promoted the formation of carbon nanofibers. The crystal structures of the catalyst were investigated. The present results indicate that the morphologies of the carbon nanofibers have a close relation with the crystal structure of the catalysts.
