Because of its excellent properties, graphene is attracting much attention with how to produce it as well as its diverse applications. The most well known graphene production method to date is chemical vapor deposition(CVD), which is using metal catalyst template at high temperature. We found a thin carbon coating on the quartz after carbonization of some specific material without any catalyst and confirmed that it was a thin nano-graphene layer by Raman, XPS. Conventional methods mainly use small molecules such as SiC and CH4 as a carbon source. This result is remarkable in that a graphene layer is formed by a simple process using an organic compound containing a benzene ring as a carbon source. |
