Abstract
Ultra-fast synthesis of graphene has been reported by microwave assisted graphene oxide reduction. In this article, the graphene oxide was initially dried above room temperature. The initial heat treatment of graphene oxide demonstrates a distinct improvement of exfoliation rate of graphene sheets. This method provides an efficient way for mass production of high quality graphene sheets. Raman spectroscopy, scanning electron microscopy, and X-ray diffraction techniques has been used to characterize reduced graphene sheets. The quality of reduced graphene was found to be affected by the initial drying temperature of graphite oxide.
