Plane view of SEM morphology of CNTNs formed on the SiO2/n-type Si(100) stacked substrate. The growth conditions were carried out at 750°C in the alcohol ambient for 10 min, and the partial pressure was achieved in 10 Torr. Various Co/Mo acetate were premixed at (a) Co : Mo = 0.1 : 0.1 wt%, (b) Co : Mo = 0.05 : 0.05 wt%, and (c) Co : Mo = 0.02 : 0.02 wt%, respectively. Then, all Co/Mo catalysts were dissolved in ethanol with sonication for 8 hours.
