NOVELTY - Separating and purifying graphene quantum dots by using a molecular sieve comprises (i) mixing the initial graphene quantum dot solution and the molecular sieve at a certain ratio to obtain a reactant at room temperature, (ii) the reactant is centrifuged to obtain a graphene quantum dot-molecular sieve containing graphene quantum dots and (iii) adding a desorbing agent to the graphene quantum dot-molecular sieve to desorb the graphene quantum dots at 70-100 degrees C. USE - The method is useful for separating and purifying graphene quantum dots by using a molecular sieve. ADVANTAGE - The method utilizes less time and is simple.
