In this study we report the effect of various synthesis temperatures of 600 - 1000°C for the synthesis of carbon nanotubes (CNT). Bio-hydrocarbon precursor namely palm oil was utilized as a starting material by thermal vapor deposition method. Ferrocene at 5.33 wt% was directly mixed with palm oil precursor for 30 mins synthesis time. The prepared CNT was collected from the furnace wall and then characterized by field emission scanning electron microscopy, scanning transmission electron microscopy, fourier transform infrared spectroscopy and thermogravimetric analysis. The density, diameter and the purities of the CNT were found to be highly dependent on the temperature changes. The synthesis temperature of 800°C was considered to be the optimum temperature for higher quality and quantity of CNT production.

Carbon nanotubes were successfully synthesized by chemical vapor deposition method which used the liquefied petroleum gas (LPG) as carbon source and NiO powder as catalysts. The experiment was carried out by heating catalyst at 450°C for 0.5 h and synthesized CNTs at 750°C for 1-5 h in tube furnace using the LPG rates of 5-20 ml/min. The product was characterized by carbon yield product, SEM, TEM, Raman, XRD and the electrical resistivity. It was found that the yield product increased with increasing the synthesis of time and the mean diameter in the range of 20 nm to 50 nm. The optimum condition of the synthesis of CNTs was found at LPG flow rate of 10 ml/min, synthesis time of 4 h and obtained the electrical resistivity of 0.62 Ω.cm.
