Popis: To gain insights into formation of carbon nanotubes (CNTs) via pyrolysis of ferrocene and glycerol, experimental analyses on chemical constituents and theoretical investigation using a fundamental mathematical model based on thermodynamics and kinetics were conducted. A systematic calculating algorithm was verified based on comprehensive data sets of previous experimental works. Effects of synthesis time, initial concentration of ferrocene and glycerol as well as temperature on the CNT formation were analyzed. The proposed model reveals that with temperature above 700 K, the formation rate of CNTs rises rapidly. However, the CNT formation rate starts to decrease slightly when the temperature exceeds 1000 K due to the competitive step of their reversible decomposition.
