1. the hydrothermal preparing process of a water-soluble graphene quantum dot, it is characterized in that this method is the aqueous solution that adds 0.01~

  • 1.0M poly-hydroxy carbohydrate in hydrothermal reaction kettle, under 120~

    220 ℃

    of temperature, heated 10~

    600 minutes, allow glycan molecule shrink to aggregate into the graphene quantum dot that is of a size of 1~

    10nm and be prepared into.
