Show Abstract
The dependence of the growth kinetics of carbon nanotubes (CNTs) on the size of the Fe-catalyst in the H2 assisted atmospheric pressure chemical vapor deposition was studied. A growth interruption method was used to determine the in situ growth rate. The formation of a compact scale contaminant layer around the catalyst hinders the diffusion of the reactant species required to grow the CNTs. The high temperature metal oxidation behavior observed using parabolic curve fitting was attributed to the size dependent catalyst activity. The parabolic rate constant shows linear dependence on the catalyst size. Details of the analysis are presented.
