NOVELTY - Method for preparing carbon nanofibers with a graphene structure on the surface, involves (A) electrostatic spinning to prepare carbon fiber precursor comprising (a) dissolving the spinning aid in the solvent to obtain the spinning solution after fully stirring, (b) adding calcification or calcium sulfite containing polymer to the spinning solution, and fully stirring to obtain the precursor spinning solution, and (c) injecting the above-mentioned precursor spinning solution into the needle tube, and preparing the carbon fiber precursor by electrostatic spinning, (B) pre-oxidizing the carbon fiber precursor at a temperature of 150-300 degrees C for 60-180 minutes, (C) carbonizing the pre-oxidized carbon fiber precursor to prepare carbon nanofibers with calcium sulfide nanoparticles coated on the graphite carbon layer on the surface, and (D) washing the carbon fibers after carbonization with water or acid. USE - The method is used for preparing carbon nanofibers with graphene structure on the surface, which is used in the fields of energy storage, catalysis and adsorption. ADVANTAGE - The method retains the surface graphite carbon layer and increases the conductivity of the carbon fiber.
