富烯碳原子簇的石墨层间闭合形成机理

GRAPHITE──LAYERS──CLOSED MECHANISM OF FULLERENES FoRATION

本文提出了富烯碳原子簇的石墨层间闭合形成机理，由该机理推出的许多结果与实验事实符合很好。我们认为碳原子簇自由基的快速淬灭及其淬灭速度是富烯碳原子簇形成及其丰度的决定因素。由此得出富烯碳原子簇在给定实验条件下产生的必然性，并预言不同大小的富烯碳原子簇可以通过优化实验条件选择性地合成。

In this paper,a graphite─layers─closed mechanism of fullerenes formation is proposed,which is fairly consistent with many experimental results.We believe that the rapid guenchingand the guenching speed of carbon─cluster radicals are critical in formation and abundance offullerenes and conclude that the formation of fullerenes is inevitable under given experimentalconditions. It is likely that varied size fullerenes could be prepared selectively by using optimumconditions.
