Fabrication of Nano Hollow Graphene Oxide Spheres via Water-in-oil Emulsion
Nano hollow 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 nano hollow graphene oxide spheres would be good candidates for catalyst supports, drug delivery and electrode materials in lithium-ion batteries.
