Growth control and modification of functionalized sites into single walled carbon nanotube

以芳香族分子为碳源，采用化学气相沉积法成功合成了石墨烯片。此外，单壁碳纳米管（SWCNTs）的电化学路线，通过施加一个小的负电位的乙酸溶液在Au表面支持镍纳米催化剂。拉曼光谱和扫描探针显微镜观察的催化剂和沉积的样品，并显示，催化剂的结构强烈影响单壁碳纳米管的直径分布。沉积碳的结构取决于催化剂的颗粒尺寸和结构。

Graphene sheet was successfully synthesized by chemical vapor deposition using aromatic molecule as carbon feedstock. In addition, single-wall carbon nanotubes(SWCNTs) were produced by an electrochemical route by applying a small negative potential to a solution of acetic acid over a Au surface supporting Ni nanocatalysts. Raman spectroscopy and scanning probe microscopy observations of the catalyst and as-deposited samples and revealed that the catalyst structure strongly affects the SWCNT diameter distribution. The deposited carbon structure depended on the catalyst particle size and structure.
