A 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. A high-quality, high-efficiency, green and energy-saving graphene production method comprises the following steps: (1) Preparation of hydrogen and oxygen: Photocatalytic decomposition of water to prepare hydrogen and oxygen for use; (2) preheating stage: take the hydrogen and oxygen prepared in step (1) and mix them with carbon sources, release current to the mixture of hydrogen, oxygen and carbon sources for preheating, so that The carbon source heats up and reaches the ignition point of hydrogen, and the hydrogen burns violently under the combustion aid of oxygen; (3) Excitation stage: release current to the mixture of hydrogen, oxygen and carbon source for the first excitation. The high-quality, high-efficiency, green and energy-saving graphene production method realizes the green and energy-saving production of graphene on the basis of ensuring the quality of graphene, and the high-quality, high-efficiency, green and energy-saving graphene production device can simultaneously realize the required Energy-efficient production of gases and the purpose of using electric fields to control reactions of carbon sources.
