NOVELTY - A vacuum energy-production of sponge body graphene comprises adding graphite rod into reaction chamber of vacuum reactor, and subjecting to electric arc ionization at 10000-13000 degrees C. USE - Method for vacuum energy-production of sponge body graphene (claimed). ADVANTAGE - The method can produce high purity 0.34-1.3 nm thick single-layer graphene under the condition of low voltage and small current, and has product obtaining rate of more than 30%, and low cost and energy consumption. The product is not easy to be oxidized, contains zero-dimensional fullerene, one-dimensional carbon nanotube, two-dimensional graphene, three-dimensional super-nano-graphite crystal, and has good performance and dispersibility, good magnetic performance, and no pollution.
