Graphene Sheets: Gram‐Scale Synthesis of Graphene Sheets by a Catalytic Arc‐Discharge Method (Small 8/2013)

Gram-scale amounts of high-quality graphene sheets are synthesized on page 1330 through an arc-discharge method. An arc, which is generated between two graphite rods when a high voltage is applied by Y. Liu and co-workers, can cause the graphite layers to separate into graphene sheets via a high-temperature exfoliation, or even broken into small clusters/atoms, which then form graphene sheets by catalytic growth, demonstrating that two mechanisms exist in an arc discharge process simultaneously.
