▎ 摘  要

NOVELTY - Preparation of large size single crystal graphene, involves using certain oxygen content copper foil as a growth substrate, and making copper foil into a cavity structure, using chemical vapor deposition process, heat-treating the structure of the copper cavity with hydrocarbon as carbon source under the protection of the non-reactive gas, and growing large size single crystal graphene by catalytic pyrolysis using carbon source gas at high temperature. USE - Preparation of large size single crystal graphene (claimed). ADVANTAGE - The preparation process is simplified, and production cost is reduced. The product quality is high, and the graphene is obtained with large size and uniform and excellent repeatability.
