▎ 摘　　要

NOVELTY - Preparation of oil-soluble graphene quantum dot, involves adding citric acid to container, melting at 180-250 degrees C until citric acid turns orange, adding oleylamine to orange citric acid, reacting for 3-8 minutes, heating at 180-250 degrees C, stop heating, adding toluene and water to heated solution, mixing completely, leaving obtained mixed solution still, stratifying, removing upper layer and freeze-drying. USE - Preparation of oil-soluble graphene quantum dot. ADVANTAGE - The method enables preparation of oil-soluble graphene quantum dot with high purity. The preparation method is simple.
