Achieving high specific charge capacitances in Fe3O4/reduced graphene oxide nanocomposites
Open accessAbstract
We report a facile approach to synthesize nanocomposites with Fe3O4 nanopaticles (NPs) attached to reduced graphene oxide (rGO) sheets by a solvothermal process, which combines the growth of Fe3O4 NPs and the reduction of GOs in one single step. These Fe3O4/rGO nanocomposites were further used to fabricate thin film supercapacitor electrodes by using a spray deposition technique without the addition of insulating binders. It was found that the Fe3O4/rGO nanocomposites showed much higher specific capacitances than that of either pure rGO or pure Fe3O4 NPs. We further carried out electrochemical characterization of the Fe3O4/rGO nanocomposites with different Fe3O4 : rGO weight ratios (e.g. IFe3O4 : rGO) and showed that Fe3O4/rGO nanocomposites with IFe3O4 : rGO = 2.8 exhibited the highest specific capacitance of 480 F g−1 at a discharge current density of 5 A g−1 with the corresponding energy density of 67 W h kg−1 at a power density of 5506 W kg−1. These Fe3O4/rGO nanocomposites also showed stable cycling performance without any decrease in the specific capacitance after 1000 charge/discharge cycles.

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.
