▎ 摘　　要

Some outstanding properties of nitrogen-doped graphene are sketched, and the latest synthesis methods, characteristic techniques and applications of nitrogen-doped graphene are reviewed. The synthesis methods of nitrogen-doped graphene mainly include chemical vapor deposition, heat treatment in ammonia atmosphere, nitrogen plasma discharge method, arc-discharge of carbon electrodes, electrothermal synthesis, solvothermal synthesis and conversion of N-containing precursors. Meantime, various characterization techniques, such as XPS, Raman, TEM, SEM and AFM, are introduced. Subsequently, the promising applications of nitrogen-doped graphene in the fields of lithium-ion batteries, lithium-air batteries and supercapacitor electrodes and oxygen reduction catalysts of fuel cells are present. Finally, some possible scientific issues involving nitrogen-doped graphene are briefly reviewed.
