▎ 摘　　要

NOVELTY - Preparing nitrogen-doped graphene, involves preparing an amino group-containing 1,3,5-triazine copolymer by using an amino group-containing 1,3,5-triazine compound. The monomer is dissolved in a solvent, an initiator is added and reacted for 2-12 hours with stirring at 0-10 degrees C to polymerize. The polymerization product is filtered and dried, and the obtained polymer solid is subjected to milling under inert atmosphere protection, heated to 600-1200 degrees C for 0.5-5 hours, then cooled to room temperature, and then processed to obtain a nitrogen doped graphene. USE - Method for preparing nitrogen-doped graphene (claimed). ADVANTAGE - The method enables to prepare nitrogen-doped graphene in a simple, eco-friendly, cost effective and easy process, under mild reaction conditions which is suitable for industrial production. The nitrogen doped graphene material shows excellent performance.
