▎ 摘　　要

This letter proposes a novel strategy for synthesis of nitrogen-doped graphene with microwave assisted. We prepared graphite oxide via Hummers method with flake graphite as raw material. Then nitrogen-doped graphene was synthesized by microwave processing of functional graphene sheets (FGS) which is obtained by treating graphite oxide with ethylenediamine (EDA). The nitrogen-doped graphene presents outstanding structure properties. The results showed that nitrogen-doped graphene sheets (NGS) can be successfully synthesized and doped with nitrogen in this method. The synthesized nitrogen-doped graphene was transparent and wrinkled.
