Electrochemical Analysis of Graphene Oxide and Reduced Graphene Oxide for Super Capacitor Applications
Abstract
Graphene Oxide (GO) was successfully synthesized by following the Hummer's method and was reduced to form reduced Graphene Oxide (rGO) by using Zn metal powder. The AFM image showed smooth surface for both GO and rGO, indicating the formation of GO sheets. The reduction in lattice spacing from 0.85 to 0.36 nm in rGO is caused by the removal of the oxygen-containing functional groups bonded on the surface of the graphene layers. The defect density as well as the number of stacking in rGO is reduced as compared to GO indicated by the reduction of both ID/IGand I2D/IGratio. As shown by the CV measurement the integrated area under the CV curve was increased with a rectangular shape for rGO and hence obtained better capacitance than GO. Hence, rGO has a better super capacitor property than GO. The impedance spectroscopy showed that the value of RCT is 21.84 and 30.54 ohm for rGO and GO respectively, indicating an increase in the charge transfer resistance for GO, and hence increased charge conductivity for rGO.

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.
