Introduction:
The unique properties of carbon nanotubes trigger a lot of ideas to study the
ability of the material in many fields.
Experimental:
The research started with the preparation of cobalt catalyst by using the sol-gel method,
which used cobalt acetate tetrahydrate and 2-amino ethanol solvent, followed by the actual growth of
carbon nanotube by using the prepared catalyst in alcohol catalytic CVD.
Results:
The crystal structure, microstructure, and size of particles of the resulting cobalt-based powders
were characterized by using X-ray Diffraction, Optical Microscopy, and Particle Size Analyzer,
followed by, carbon nanotube growth at 700, 750, 800, and 850°C, where other parameters were fixed
in order to determine the effect of CVD processing and temperature on the quality of resulting carbonbased
materials. The graphitic structure of the carbon-based materials was analyzed by using Raman
Spectroscopy.
Conclusion:
It was found that the optimum CVD processing temperature was 850°C with IG/ID ratio of
1.052.
