Graphene materials derived through the exfoliation of graphite are always accompanied with high population of defects and/or surface functionalities due to the harsh conditions utilized in the synthesis. We describe herein a scalable approach for the preparation of high quality graphene materials via low-temperature exfoliation of graphite under mild chemical conditions. The microwave induced rapid decomposition of nitromethane at low temperature produces mechanical force that lifts up the graphene sheets from the FeCl₃ and CH₃NO₂ co-intercalated graphite compound without creating defects and functional groups.
