NOVELTY - Preparing high nitrogen-doped graphene involves using hexamethylene tetramine with zinc salt to reacting in solvent after filtering or centrifuging, and unreacted raw material by solvent, drying to obtain hexamethylene tetramine/zinc coordination polymer precursor, where mole ratio of hexamethylene tetramine and zinc salt is 1: (0.25-10), taking obtained mixture in coordination polymer precursor, and gradually heating at 200-1000 degrees C under an inert atmosphere for 1-5 hours to obtain high nitrogen doped graphene. USE - Method for preparing high nitrogen-doped graphene. ADVANTAGE - The method enables to prepare high nitrogen-doped graphene which is widely used in field of preparing high nitrogen-doped graphene.
