Abstract

In this paper we have investigated the synthesis of carbon nanotubes by catalytic atomizer system or spray pyrolysis which is type of catalyzed chemical vapor deposition method. The advantages use this method consist in the direct and continuous generation of fresh catalytic particles throughout the entire growth. This system method using palm oil as the carbon source and the ferrocene Fe(C5Hs)2 as the catalyst precursor which process is based on the decomposition of hydrocarbon in a reaction furnace. The thermal decomposition of ferrocene solution was realized in an argon atmosphere. The material was characterized by Field Emission Scanning Electron Microscope (FE-SEM), Thermo gravimetric Analysis (TGA) and Raman Spectroscopy. CNTs were found to grow at 750°C. At a temperature of 750° C using FE-SEM, CNTs were found as a look likes "bamboo" structure. At a temperature of 750° C using Raman spectroscopy, the carbon G and D peaks were prominent at 1540 cm"1 and 1306 cm"1 respectively. The ratio of the intensities of these peak, IQ/ID was found is 1.18. The best curve in the temperature at a 750° C and other temperatures a few amount of amorphous carbon in CNTs using TGA.
