NOVELTY - Separating graphene quantum dots using molecular sieves involves placing corresponding molecular sieve inside the syringe and compact on the bottom of the syringe, pouring the initial graphene quantum dot solution into the syringe, squeezing the syringe forcefully to squeeze out all the solution in the syringe to obtain a quantum dot solution within a certain size range, adding a certain amount of eluent into the syringe, and then squeezing all the solution in the syringe, repeating elution for 3-5 times, taking out the molecular sieve, and eluting the graphene quantum dots adsorbed on the surface of the molecular sieve and embedded in the molecular sieve, replacing the molecular sieve with a larger pore size inside the syringe, repeating the above steps 1-5 and then replacing the molecular sieve with a larger pore size to obtain final product. USE - Method for separating graphene quantum dots using molecular sieves. ADVANTAGE - The method enables to separate graphene quantum dots using molecular sieves has high purity.
