NOVELTY - Method for preparing N-containing graphene material involves taking N-containing six-membered heterocyclic compound and metal acetylide as raw materials, and using ethanol as the solvent, carrying out the ultrasonic reaction under the conditions of an ultrasonic frequency of 50-55 kHz, separating after the reaction is completed, washing the collected solids and drying to obtain the N-containing graphene material. USE - The method is used for preparing N-containing graphene material. ADVANTAGE - The method is simple to operate, mild in conditions, environmentally-friendly, and has low requirements for equipment.
