摘要

我们报道了以混合稀土(几种稀土元素的天然混合物)为催化剂，在高密度下形成碳纳米管(CNTs)。人们发现，与镧(La)或铈(Ce)相比，Mm是一种更好的催化剂。当催化剂La在非常高浓度(~ 90wt.%)下使用时，复合纳米棒的形成也被描述和讨论。

SYNTHESIS OF CARBON NANOTUBES THROUGH CARBON ARC EVAPORATION EMPLOYING Mm, La, AND Ce CATALYSTS

We report the formation of carbon nanotubes (CNTs) in, high density when mischmetal Mm (a natural mixture of several rare earth elements) is used as catalyst. Mm has been found to work as a better catalyst than either lanthanum (La) or cerium (Ce). The formation of composite nanorods when the catalyst La is used in very high concentration (∼90wt.%) has also been described and discussed.
