摘要

以二十面体对称性Co55团簇为基体，采用密度泛函理论系统计算研究了Mo原子处于不同替代(掺杂)位时，Co-Mo团簇体系与不同手征性((10

0)及(5

5))单壁碳纳米管的相互作用．结果表明：Co-Mo混合团簇体系与单壁碳纳米管的相互作用与掺杂Mo原子在团簇中的位置(内部或表面)及单壁碳纳米管的手征性(对称性)密切相关．相较纯Co55团簇，Mo原子掺杂团簇对于单壁碳纳米管具有明显增强的结构调控作用，这对单壁碳纳米管的结构可控性合成具有启示作用．

Abstract

Based on the basic structural motif of the icosahedral symmetric Co55cluster

the interaction between the Co-Mo clusters with a Mo atom at different substituting sites and single-walled carbon nanotubes with different chiralities((10

0) and(5

5)) was studied by density functional theory calculations. The results show that the interaction between the system of Co-Mo mixed cluster and single-walled carbon nanotubes is strongly correlated with the location of the doped Mo atom in cluster and the chirality of the single-walled carbon nanotube. Compared with pure Co55 clusters

Mo atom doped clusters have obvious enhanced structural control effect on single-walled carbon nanotubes

which has enlightenment for the controllable synthesis of single-walled carbon nanotubes.
