High-quality, high-efficiency, green and energy-saving graphene production method and device

Abstract

The invention discloses a high-quality, high-efficiency, green and energy-saving graphene production method and device. The high-quality, high-efficiency, green and energy-saving graphene production method comprises the following steps: (1) preparation of hydrogen and oxygen: preparing hydrogen and oxygen by photocatalytic decomposition of water through sunlight for later use; (2) a preheating stage: mixing the hydrogen and the oxygen prepared in the step (1) with a carbon source, releasing current to the mixture of hydrogen, oxygen and the carbon source for preheating, heating the carbon source to reach the ignition point of hydrogen, and intensely combusting hydrogen under the combustion-supporting action of oxygen; and (3) an excitation stage: releasing current to a mixture of hydrogen, oxygen and the carbon source to carry out first excitation. According to the high-quality, high-efficiency, green and energy-saving graphene production method, green and energy-saving production of graphene is achieved on the basis that the quality of graphene is guaranteed, and the high-quality, high-efficiency, green and energy-saving graphene production device can achieve the purposes of energy-saving production of needed gas and control over carbon source reaction through an electric field at the same time.
