Fabrication of Nano Hollow Graphene Oxide Spheres via Water-in-Oil Emulsion

Abstract:

nanohollow graphene oxide spheres have been successfully fabricated from graphene oxide nanosheets utilizing a water-in-oil emulsion technique. High quality graphene oxide nanosheets were prepared from natural flake graphite by oxidation and ultrasonic treatment. Graphene oxide nanosheets were supported by the water-in-oil interface, and self-assembled around water droplets under the assistance of ammonia. With the removal of aqueous ammonia, the graphene oxide nanosheets stacked and condensed at the water-in-oil interface and finally formed a shell structure around the soft template. The nanohollow graphene oxide spheres would be good candidates for catalyst supports, drug delivery and electrode materials in lithium-ion batteries.
