Growth of Bamboo like Carbon Nanotubes from Brassica Juncea as Natural precursor
J. Environ. Nanotechnol., Volume 3, No 2 (June 2014) pp. 92-100
Abstract
Bamboo like Carbon Nanotubes with compartments were synthesized using Brassica Juncea over Fe-Mo impregnated alumina support at 650 0c reaction temperature 20ml/hour gas flow rate and at normal pressure under N2 atmosphere. In this experiment we achieved maximum yield of entangled carbon nanotubes from the taken precursor. Morphological and Structural studies have been performed by FESEM, HRTEM and Raman Spectroscopic analysis. We identified the growth of carbon nanotube structures with compartments on the chosen catalytic support material. The diameter of multi-walled carbon nanotubes is found in the range of 60 to 80nm. Tip growth mechanism has been observed from the TEM images. We conclude that the Brassica Juncea material has been found to be valuable precursor for the synthesis of low cost and high quality multi-walled carbon nanotubes for large scale production.
