Single-walled carbon nanotubes (SWCNTs) have been successfully synthesized by chemical vapor deposition (CVD) using acetylene (C<sub>2</sub>H<sub>2</sub>) gas as a carbon source and a mixture of Fe/Mo/Co on an Al<sub>2</sub>O<sub>3</sub> support as a catalyst. The effects of the weight percentage (wt%) of metals in the Fe/Mo/Co/Al<sub>2</sub>O<sub>3</sub> catalysts, growth time, gas flow rate and growth temperature on SWCNT growth were studied in detail. The optimum growth conditions were found to be a growth time of 60 min, a growth temperature of 750 °C, Ar/H<sub>2</sub>/C<sub>2</sub>H<sub>2</sub> flow rates of 420/100/14 sccm and a catalyst composition of Fe/Mo/Co/Al<sub>2</sub>O<sub>3</sub>=5/3/1/80 (wt%). The morphologies and structures of the grown SWCNTs were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Raman spectroscopy techniques. |
