Porous graphene, graphene quantum dot and green preparation method for porous graphene and graphene quantum dot
A porous graphene, a graphene quantum dot and a green preparation method for the porous graphene and the graphene quantum dot. The method includes adding a starting material, graphite, into an acetic acid aqueous solution of chitosan, using chitosan as a stripping agent, obtaining the porous graphene by an ultrasonic treatment, centrifugation and precipitation, and obtaining the graphene quantum dot by dialyzing a supernatant from the centrifugation. The obtained porous graphene has fewer layers and a larger lateral dimension of sheet. The obtained graphene quantum dot has good dispersity and a uniform particle size distribution. The preparation method is simple to perform and a graphitization degree of the prepared porous graphene and graphene quantum dot is high. The obtained porous graphene can be used as a carrier for a reverse gene transfection, and the graphene quantum dot can be used for cell imaging.
