Multi-directionally grown carbon nanofibers prepared by catalitic combustion technique

A simple synthesis technique for direct synthesis of multi-directionally grown carbon nanofibers had been depicted using methanol catalytic combustion technique at room temperature without using any template substrate. The precursor gas used was methanol, which provide carbon source necessary for the formation of the multiple-directional carbon nanofibers and reaction conditions necessary for synthesis of the multi-directional grown carbon nanofibers. Copper plate was used as the substrate and nickel nitrate as the precursor. Scanning electron microscopy characterization clearly shows the multi-directional structures. The composition of catalyst was analyzed by the energy dispersion X-ray spectroscopy. Transmission electron microscopy examination indicates the CNF have a good microstructure.
