以乙烯为碳源，碳纳米管负载铁基为催化剂，于790℃制备了平均直径约为30nm的多壁碳纳米管。研究了700～850℃范围内碳纳米管产物的形貌特征和纯度，并与以Al2O3负载铁基作为催化剂的产物进行了比较。利用SEM、TEM、拉曼光谱，对催化剂和产物进行了表征，发现在最佳反应温度下，两种催化剂制备的碳纳米管形貌、直径分布范围及平均直径相当，但以碳纳米管负载铁基为催化剂，产量明显提高100％，且不具有难处理的氧化物载体，纯度很高。

The synthesis of multi-wall carbon nanotubes（MWNTs） with the average diameter of 30 nm, using Fe/CNTs as catalyst via the catalytic decomposition of ethylene at 790℃, was reported. The morphologies and purity of CNTs obtained at different temperatures from 700～850℃ as well as the products obtained using Fe/Al2O3 as catalyst were investigated. SEM, TEM, Raman spectroscopy were used to characterize the catalyst and products. In addition to the same morphology and the accordant diameter like the products obtained from Fe/Al2O3 catalyst, the y...
