Abstract : Multiwalled carbon nanotubes with high crystallinity and purity were synthesized with acetylene as the carbon source using radio frequency catalytic chemical vapor deposition method (RF-CCVD) and a bimetallic Fe-Co catalyst supported on CaO at 720°C. The sample obtained was tested using Raman spectroscopy, high resolution transition electron microscopy (HRTEM) and thermogravimetric analysis (TGA). The Raman spectra revealed G to D band and 2D to G band intensity ratios of 0.90 and 0.54 respectively. A purity of 90% was obtained from the TGA studies. HRTEM studies further showed that the nanotubes had an average diameter of 14.7 ± 4.76nm.
