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.

为了深入了解通过二茂铁和甘油的热解形成碳纳米管 (CNT)，使用基于热力学和动力学的基本数学模型对化学成分进行了实验分析和理论研究。基于先前实验工作的综合数据集验证了系统的计算算法。分析了合成时间、二茂铁和甘油的初始浓度以及温度对CNT形成的影响。所提出的模型表明，当温度高于 700 K 时，CNT 的形成速率迅速上升。然而，由于其可逆分解的竞争步骤，当温度超过 1000 K 时，CNT 的形成速率开始略有下降。
