摘 要:Nano hollow graphene oxide spheres have been successfully fabricated from graphene oxide nanosheets utilizing a water-in-oil emulsion *** quality graphene oxide nanosheets were prepared from natural flake graphite by oxidation and ultrasonic *** oxide nanosheets were supported by the water-in-oil interface,and self-assembled around water droplets under the assistance of *** 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 *** nano hollow graphene oxide spheres would be good candidates for catalyst supports,drug delivery and electrode materials in lithium-ion batteries.
