To provide a simple process for producing graphene. n A graphene production apparatus 100 has a vessel 10 and, attached thereto, an immersion electrode 20 and a non-immersion electrode 30 . The immersion electrode has an electrode covering 20 c and an electrode main body 20 e , and the non-immersion electrode has a covering 30 c and an electrode main body 30 e . An argon-feeding conduit 40 is disposed so as to inject argon into the vessel 10 around the electrode main body 30 e . Ethanol is supplied in such an amount that the liquid surface completely covers the electrode main body 20 e of the immersion electrode 20 and does not reach the electrode main body 30 e of the non-immersion electrode 30 . The electrode main body 20 e is formed from, for example, iron, nickel, or cobalt. Thus, a 60-Hz AC voltage is applied to the electrode main body 20 e immersed in the liquid; i.e., below the ethanol surface, and to the electrode main body 30 e located above the liquid, while argon gas is supplied through the argon-feeding conduit 40 . As a result, a gas-liquid plasma generates, to thereby induce decomposition of ethanol, etc., whereby graphene is yielded. The graphene disperses in ethanol. |
