单壁碳纳米管（SWNTs）与Cr（CO）6和苯-Cr（CO）3的溶液相反应可导致小的铬簇的形成。通过增加反应时间，簇尺寸可以从小于1 nm变化到约4 nm。TEM图像表明，簇主要沉积在纳米管的外壁上。TGA分析用于获得Cr络合的SWNT中的Cr含量和碳铬比。有人建议，碳纳米管苯型结构模板的铬原子的缩合，并促进一氧化碳的损失，导致良好定义的金属簇。
The solution phase reactions of single-walled carbon nanotubes (SWNTs) with Cr(CO)6and benzene-Cr(CO)3can lead to the formation of small chromium clusters. The cluster size can be varied from less than 1 nm to about 4 nm by increasing the reaction time. TEM images suggest that the clusters are deposited predominantly on the exterior walls of the nanotubes. TGA analysis was used to obtain the Cr content and carbon to chromium ratio in the Cr-complexed SWNTs. It is suggested that the carbon nanotube benzenoid structure templates the condensation of chromium atoms and facilitates the loss of carbon monoxide leading to well defined metal clusters.
