烃和CO气相沉积制备多壁碳纳米管的热力学条件

摘要利用俄罗斯科学院研制的CVD(chemicalvapordeposition)软件计算了在101×103Pa和700K～1500K烃催化热解以及在101×103Pa和700K～1200KCO催化热解影响碳沉积率的因素,并根据碳沉积相边界点的反应物组成绘制了碳沉积边界曲线,预测了碳沉积区,计算结果对多壁碳纳米管的制备提供了有关的信息。

Abstract： Influences on the percentage of deposited carbon from hydrocarbon via chemical vapor deposition at 700 K to (1 500 K,)101×10~3 Pa and CO via chemical vapor deposition at 700 K to (1 200 K),101×10~3 Pa were calculated by use of the CVD (chemical vapor deposition) software developed by the scientists of Russia Academy of Science.And curves of the phase boundary of carbon deposition were drawn according to the composition of reactants at the phase boundary of carbon deposition.The carbon deposition area was predicted.Catalysts suitable for different situations were selected.The calculated results provided useful references for the preparation of multiwall carbon nanotubes.
