NOVELTY - Production of a multilayer graphene carbon material comprises preparing a liquid precursor comprising (wt.%) resorcinol (1), formaldehyde aqueous solution (0.8-3.5), hexadecyl trimethyl ammonium bromide (0.004-0.07), deionized water (0-7.5), and metal acetate (0.5-50); heating the liquid precursor to obtain a solid precursor; heating the solid precursor in a tubular furnace to obtain an amorphous carbon material; and heating the amorphous carbon material and sodium metal in a furnace under the protection of nitrogen, cooling to room temperature, washing with water, and drying at 100 degrees C. USE - Method for the production of a multilayer graphene carbon material (claimed) used for a sensor, a capacitor, a catalyst, and energy storage. ADVANTAGE - The method converts the self-made amorphous carbon material to be a multilayer graphene under low temperature and normal pressure, inhibits increase of carbon layer stacking amount during the carbon atom reforming process, and avoids multiple layer graphene structure reforming process obtained in a large amount into the graphite crystal. DETAILED DESCRIPTION - Production of a multilayer graphene carbon material comprises: (A) preparing a liquid precursor by uniformly mixing (wt.%) resorcinol (1), formaldehyde aqueous solution (0.8-3.5), hexadecyl trimethyl ammonium bromide (0.004-0.07), deionized water (0-7.5), and metal acetate (0.5-50), where the formaldehyde aqueous solution contains 37-40% water, where the metal acetate is manganese acetate, cobalt acetate, nickel acetate, ferrous acetate, copper acetate, or zinc acetate; placing the liquid precursor in a reaction bottle, sealing, heating for 12 hours to 9 days at 60-90 degrees C, drying for 5 hours to 9 days at room temperature, and drying for 2-36 hours at 60-100 degrees C to obtain a solid precursor; placing the solid precursor in an inert material crucible, placing the crucible in a tubular furnace under the protection of nitrogen or argon gas, heating to 500-1000 degrees C, keeping the temperature for 1-72 hours, and cooling to room temperature to obtain an amorphous carbon material; and (B) placing the amorphous carbon material and elemental sodium metal at a mass ratio of 3-7:7-3 in an inert material crucible, placing the inert material crucible in a tubular furnace, heating to 500-1000 degrees C under the protection of nitrogen or argon gas at 1-50 degrees C/minute, keeping the temperature for 1-72 hours, cooling to room temperature, taking out the product, washing with 65-68 mass% nitric acid and deionized water, where the pH value of the solution is 7, and drying at 100 degrees C, where the inert material crucible is made of alumina, silicon nitride, aluminum nitride, boron nitride, or silicon carbide.
