Research Abstract

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.
