Figure 3.9 Kinetics of CNT growth with purified feed gases. (A) Arrhenius plot of initial growth rates. The activation energy was calculated
from the slope of the line. (B) Plot of initial growth rates (40% constant hydrogen) with respect to carbon precursor (ethylene)
variation. The inset shows the enlarged plot near the origin. (C) Plot of initial growth rates (10% constant ethylene) with
respect to hydrogen variation. In these experiments, the total flow rate was maintained at 1000 SCCM under 1 atm.
