A method for repairing a reduced graphene oxide, is characterized in comprising the following steps: Dispersing the reduced graphene oxide into a solvent to obtain a graphene dispersion liquid, adding a first Lewis acid and a compound containing a methyl or methylene group to obtain the first mixture, reacting the first mixture in a microwave environment of which power is 300~900w for 0.5~2 hours, refluxing for 3-5 hours; separating, purifying and drying to obtain the first crude product; Adding the first crude product into a second Lewis acid, adding an aromatic hydrocarbon repairing agent to obtain the second mixture, reacting the second mixture to obtain a molten solid, separating and purifying same to obtain the second crude product; Mixing the second crude product, a metal powder catalyst and a third Lewis acid to obtain the third mixture, reacting the third mixture in the atmosphere of a protection gas containing a carbon source at a temperature of 450-500 °C for 1-2 hours, and annealing in a vacuum environment for 5-8 hours under the temperature of 200°Cˆ¼350°C, this method can repair reduced graphene oxide effectively. |
