Gas flow and temperature synthesis dependence on the CNTs structure and yield

Recently, research on CNTs received great attention because of their potential applications in field emission, energy storage, chemical sensors and microelectronic devises. The study in this paper is based on the comparison between EtOH and C2H4 decomposition over Fe-Co/MgO support using different gas flow and at different synthesis temperature. So, we have systematically studied the effect of EtOH, C2H4 and synthesis temperature on the CNTs structure and yield using the CCVD process. The CNTs yield increases significantly with increasing gas flow. In addition, with reactor temperature above to 900 °C, we obtain more SWCNTs than MWNTs using EtOH and ethylene, as carbon precursor, respectively. Finally, the obtained products were qualitatively characterized by TEM and FESEM.
