Growth of CNTs using liquefied petroleum gas as carbon source by chemical vapor deposition method

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...

Description
Summary: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. © (2013) Trans Tech Publications, Switzerland.
