Extraordinary fast synthesis method of graphene – Microwave based - nitronium ions enabled

Currently researchers are using Hummers method[1] or improved graphene oxide[2] synthesis routing to preparation of graphene oxide. But unfortunately these conventional methods is consisted with disadvantages of slash sheets into small pieces and/or occurrence of nanometer-sized holes in the basal plane. As we experience these conventional methods are time consuming too.

Chiu P. L et al recently (March 2, 2012) reported an extraordinary fast and scalable approach to avoid above problems.  KMnO4 has intentionally removed from the process, and microwave heating has been utilized to combine its unique properties with aromatic oxidation by nitronium ions.
