Hollow graphene oxide spheres self-assembled by W/O emulsion
Abstract
Hollow graphene oxide spheres (HGOSs) were fabricated from graphene oxide nanosheets (GONs) utilizing a water-in-oil (W/O) emulsion technique without surfactant. Effects of oxidation treatment and water removal on the formation and morphology of HGOSs are investigated. The oxidation time for preparing GONs is a crucial factor for the formation and morphology of HGOSs. We found that with increasing oxidation time, the morphology and surface topography of HGOSs vary from irregular and rough to uniform and smooth shape with decreasing diameter. Moreover, the electrochemical performance of HGOSs as anode materials in lithium-ion batteries was evaluated. The heat-treated HGOSs exhibit a 485 mAh g−1 reversible capacity and high rate performance thanks to the hollow structure, thin and porous shells consisting of graphene.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
