NOVELTY - Continuous and stable production of large-area graphene involves providing a reaction furnace containing a molten solvent, heating the solvent to form a high-temperature region and a low-temperature region with a temperature difference between the solvent and the high-temperature region in the reaction furnace, and including a transition temperature region which is located between the high-temperature region and the low-temperature region, in which the temperature difference between the high temperature region and the low temperature region is at least 30 degrees C, the temperature difference between the transition temperature region and the low temperature region is at least 20 degrees C, and adding a carbon source and alkali metal into the high-temperature region and mixing with the solvent to form an initial solution. USE - Continuous and stable production of large-area graphene. ADVANTAGE - The method enables continuous and stable production of large-area graphene with improved quality. DETAILED DESCRIPTION - Continuous and stable production of large-area graphene involves providing a reaction furnace containing a molten solvent, heating the solvent to form a high-temperature region and a low-temperature region with a temperature difference between the solvent and the high-temperature region in the reaction furnace, and including a transition temperature region which is located between the high-temperature region and the low-temperature region, in which the temperature difference between the high temperature region and the low temperature region is at least 30 degrees C, the temperature difference between the transition temperature region and the low temperature region is at least 20 degrees C, and adding a carbon source and alkali metal into the high-temperature region and mixing with the solvent to form an initial solution, flowing the initial solution from the high-temperature region through the transition temperature region to the low temperature region to form a supersaturated solution, and precipitating on a surface of the supersaturated solution.
