The Effect of Temperature on Carbon Nanotubes Synthesized using Trimetallic Catalyst from Waste Cooking Palm Oil Precursor
In this study, we investigate the effects of synthesis temperature ranging from 650-900° C on carbon nanotubes (CNT) morphology. The synthesis was performed using thermal chemical vapor deposition method. Waste cooking palm oil was used as an economical and bio-hydrocarbon precursor. The Fe-Ni-Co catalyst was used as trimetallic catalyst which was deposited using spin coating method. The samples were analyzed using scanning electron microscope, micro-Raman and Fourier transform infrared spectroscopy. The analysis shows that the synthesis temperature significantly affects the density, diameter and quality of the CNT produced. The synthesis temperature of 750° C was considered the optimum temperature for smaller diameter CNT and good crystallinity (ID/IG ~0.82).
