▎ 摘　　要

NOVELTY - Preparing high dispersible nitrogen doped graphene involves taking expanded graphite, sodium nitrate and potassium permanganate in mass ratio of (1-2):1:6, and dispersing in concentrated sulfuric acid, and then stirring the mixture for 8-20 hours to obtain suspension. Hydrogen peroxide and dispersing agent are added to suspension, and then stirred for 30 minutes. Formaldehyde solution and pyrrole solution are added to obtained product, and then processed in inert atmosphere protection to obtain high dispersible nitrogen doped graphene. USE - Method for preparing high dispersible nitrogen doped graphene (claimed). ADVANTAGE - The method enables preparing high dispersible nitrogen doped graphene in an easy and simple manner.
