| titleOfInvention |
A process for manufacturing graphene quantum dots and graphene quantum dots prepared therefrom |
| abstract |
It relates to a method for producing graphene quantum dots using coffee bean powder as a carbon source, and to graphene quantum dots produced thereby. An economical and high-yield graphene quantum dot can be manufactured by the manufacturing method of the present invention, and the obtained graphene quantum dot has low toxicity and is doped with nitrogen, and thus has excellent electrical properties. |
