Abstract: In this study, Carbon Nanotubes (CNTs) were produced through the Chemical Vapour Deposition (CVD) reactor with ferrocene acting as both carbon source and catalyst with argon as the carrier gas. The reaction was carried out at temperatures ranging from 800 to 950°C. Four grams of the ferrocene was placed in a vapouriser at the bottom of the reactor. The system was purged with nitrogen for 20 min to make sure there were no gas leakages as well as free from other gases. The furnace was turned on at the desired temperatures (800-950°C) to produce the CNTs. The CNTs were analysed using the Transmission Electron Microscopy (TEM) and Raman Spectroscopy. The results showed the alignment of multi walled CNTs that ranged between 100 and 1000 nm in length. Furthermore, the CNTs were produced at all the temperatures. However, the optimum temperature for the production of the CNTs was found between 850 and 900°C. The amount of CNTs produced at 800 to 950°C varied from 2.0±0.03 to 2.3±0.34 g at 95% confidence interval with no significant different at p>0.05 using the Instat Program version 5.0.1.
