▎ 摘　　要

NOVELTY - Producing graphene quantum dots, comprises (a) introducing a carbon-based layered structure into a reactor containing a solvent, (b) forming an interlayer insert composite by inserting an interlayer insert between each layer of the carbon-based layered structure, (c) placing interlayer composite on a substrate and heat-treating to weaken the interlayer attractive force of the interlayer composite, and (d) applying a voltage to the substrate to peel the intercalation composite to obtain graphene quantum dots. USE - The method is useful for producing graphene quantum dots. ADVANTAGE - The method does not use harmful chemical solvents or surfactants, is suitable to mass-produce high-quality graphene quantum dots, minimizes defects, improves electrical properties, and is simple and economical. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene quantum dots prepared by the above method.
