초록

Catalytic performance of Co catalysts supported on MgO for the formation of multiwall carbon nanotubes (MWCNTs) Having 40-60 nm in diameter has been investigated through acetylene decomposition at $600^{\circ}C$. Scanning electron microscopy measurements show that the nanotubes are chain and coiled structures whereas x-ray diffraction patterns indicate the formation of MWCNTs with Co nanoparticles. In addition Raman spectra confirms the format ion of MWCNTs due to presence of characteristic radial breathing mode along with D and G bands.
