NOVELTY - Preparing fluorine-modified fullerene/graphene heterojunction comprises reacting a free reactive group on a fullerene/graphene heterojunction with a fluorocarbon polymer resin. USE - The method is useful for preparing fluorine-modified fullerene/graphene heterojunction. ADVANTAGE - The method increases the defects of fullerene/graphene heterojunction and improves the solubility and adsorption of the material. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) producing fullerenes comprising preparing a nano-nuclear shell fullerene material by catalytic cracking of a hydrocarbon-containing gas on an iron-nickel-based catalytic material; and (2) device for preparing fullerenes comprising according to the method for preparing fullerenes according to the claims as mentioned above.
