| titleOfInvention | Graphene quantum dot and preparation method thereof |
| abstract | The invention relates to the field of graphene quantum dots, in particular to a graphene quantum dot and a preparation method thereof, wherein the preparation method of the graphene quantum dot comprises the following steps of mechanically mixing a graphite powder block with a molten salt catalyst; preheating the mixed material in the step one and preserving heat; taking the mixture subjected to heat preservation in the step two, directly heating and preserving heat; fourthly, after the mixed material in the third step is cooled to room temperature, the mixed material is soaked in water to obtain suspension; fifthly, taking the suspension in the step IV, and obtaining a graphene quantum dot product through centrifugal filtration. The preparation method of the graphene quantum dots has the advantages of low manufacturing cost, high graphitization degree and good finished product quality, and is suitable for large-scale production. |
