▎ 摘　　要

NOVELTY - Preparation of iron-nitrogen-graphene oxygen reduction catalyst based on nitrogen-rich conjugated organic matter, involves adding graphene to solvent, ultrasonically dispersing for 10-30 minutes to obtain 1.5-2 mg/mL graphene suspension, adding nitrogen-rich conjugated organic matter and iron salt to the suspension, mixing, heat-treating the formed solid under protection of inert gas at 600-1000 degrees C for 1-5 hours to obtain product as black powder. USE - Preparation of iron-nitrogen-graphene oxygen reduction catalyst based on nitrogen-rich conjugated organic matter (claimed). ADVANTAGE - The method enables simple preparation of iron-nitrogen-graphene oxygen reduction catalyst based on nitrogen-rich conjugated organic matter, by using an easy-to-operate device.
