▎ 摘 要
NOVELTY - Manufacture of graphene quantum dots from carbon source involves exposing carbon source to a solution containing an oxidant, and forming the graphene quantum dots from the carbon source. The carbon source is chosen from coal, coke, biochar, and/or asphalt. USE - Manufacture of graphene quantum dots (claimed). ADVANTAGE - The method enables economical manufacture of graphene quantum dots which are easily reproducible. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart of the manufacture of graphene quantum. Selection of carbon source process (10) Exposing process (12) Formation of graphene quantum dots process (14) Separation process (16) Enhancement of quantum yield process (18) Graphene quantum dots reducing process (20)
