Abstract
Multi-walled carbon nanotubes were synthesized using methyl ester of Madhuca longifolia oil over Fe-Mo impregnated alumina support at 650 °C under N2 atmosphere at normal pressure. Structural characterizations have been done by Field Emission Scanning Electron Microscopy (FESEM), High Resolution Transmission Electron Microscopy (HRTEM) and Raman Spectroscopic analysis. We confirmed that well graphitized multi-walled carbon nanotubes were nicely grown on the chosen catalytic supporting material. The diameter of the carbon nanotubes obtained were between 30 and 40 nm.
