▎ 摘　　要

NOVELTY - Preparing nitrogen-doped graphene using shock wave treated carbonate comprises (a) uniformly mixing carbon source, reducing agent and nitrogen source to obtain powder 1, transferring the powder 1 into a sample box and compacting to obtain a blank having compaction degree of 80-95%, (b) using flyer plate impact sample box induced chemical reaction to obtain powder 2, and (c) transferring powder 2 into a reactor, adding concentrated nitric acid, reacting at 65-80 degrees C for 12-15 hours, filtering, washing to obtain a solid, drying to obtain powder 3, which is nitrogen doped graphene. USE - The method is useful for preparing nitrogen-doped graphene using shock wave treated carbonate (claimed). ADVANTAGE - The method: provides nitrogen doped graphene with 1-6 layers, which has high nitrogen doping amount, good oxygen reduction catalyst activity; is economical, short, simple and convenient for industrial production; has low demand for production conditions; and is safe.
