| Summary: | The carbon nanotubes (CNTs) were synthesized by simple method of spray pyrolysis CVD method and their characteristics were investigated. Palm oil, a plant based precursor was used as source of carbon and Argon gas as the carrier gas. CNTs were synthesized at different deposition temperatures ranging from 500 to 900°C with interval of 100°C. At different temperatures, the characteristics of CNTs markedly changes such as the crystallinity and diameter as was confirmed by Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), and Raman spectroscopy studies. The bimetallic catalyst of cobalt (Co) and iron (Fe) supported on silica gel particles improves the quality, quantity and uniformityof CNTs. |
