NOVELTY - Method for preparing graphene-like flake nitrogen-doped porous carbon material involves (i) dissolving aniline and pyrrole in TritonX-100 (RTM: Typical non-ionic detergent) aqueous solution and stirring to obtain mixed solution (I), (ii) adding aqueous solution of ammonium persulfate to the mixed solution (I) and mixing to obtain a mixed solution (II), leaving still the mixed solution (II) to obtain reaction product, washing with water and freeze-drying to obtain aniline-pyrrole copolymer, (iii) dissolving sodium chloride in water to obtain salt solution, ultrasonically dispersing to obtain mixed solution (III), (iv) freeze-drying to obtain sintering precursor, (v) sintering it under inert gas atmosphere to obtain carbon material and (vi) immersing the carbon material in dilute sulfuric acid for acidification, taking it out and washing it to neutrality and vacuum drying it to obtain the carbon material. USE - The graphene-like sheet-like nitrogen-doped porous carbon material is used as a carrier material for lithium-sulfur battery cathode materials (claimed). DETAILED DESCRIPTION - Method for preparing graphene-like flake nitrogen-doped porous carbon material involves (i) dissolving aniline and pyrrole in TritonX-100 (RTM: Typical non-ionic detergent) aqueous solution and uniformly stirring to obtain mixed solution (I), (ii) adding an aqueous solution of ammonium persulfate to the mixed solution (I) and uniformly mixing to obtain a mixed solution (II), leaving still the mixed solution (II) to obtain a reaction product, washing the reaction product with distilled water and freeze-drying to obtain an aniline-pyrrole copolymer, (iii) dissolving sodium chloride and ferric chloride in water to obtain a salt solution, adding the aniline-pyrrole copolymer to the salt solution, and ultrasonically dispersing to obtain a mixed solution (III), (iv) placing the mixed solution (III) in a freeze-drying oven and freeze-drying to obtain a sintering precursor, (v) placing the sintering precursor in a sintering furnace and sintering it under an inert gas atmosphere to obtain carbon material and (vi) immersing the carbon material in dilute sulfuric acid for acidification, taking it out and washing it with water to neutrality, and finally vacuum drying it to obtain a graphene-like sheet-like nitrogen-doped porous carbon material.
