▎ 摘  要

NOVELTY - Preparing graphene quantum dots of supramolecular structure comprises (1) mixing phloroglucinol with deionized water, ultrasonically dispersing to completely dissolve it, (2) adding the solution into the autoclave, keeping the pressure within 6-12 MPa, controlling the temperature at 160-220degreesC, and naturally cooling after reacting for 2-15 hours to obtain a brownish-yellow solution, and (3) dropping the brownish-yellow solution on a glass sheet, placing into a blast drying oven, and drying at 60-80degreesC to obtain graphene quantum dots with a supramolecular structure. USE - The method is useful for preparing graphene quantum dots of supramolecular structure. ADVANTAGE - The method: realizes graphene quantum dot super-molecular structure with different shapes.
