Solvothermal synthesis of CoS2–graphene nanocomposite material for high-performance supercapacitors
Abstract
A CoS2–graphene nanocomposite was prepared by a facile solvothermal method. FESEM and TEM analyses have confirmed that CoS2 nanoparticles with sizes of 5–15 nm are densely anchored on graphene nanosheets. The as-prepared nanocomposite was electrochemically tested as an electrode material for supercapacitors. The CoS2–graphene nanocomposite exhibited specific capacitances of 314 F g−1 in the aqueous electrolyte and 141 F g−1 in the organic electrolyte at a current rate of 0.5 A g−1 with excellent cycling stability. The electrochemical performance of the nanocomposite has been significantly improved, compared to bare graphene nanosheets and CoS2 nanoparticles. This could be credited to the 3D nanoarchitecture, in which CoS2 nanoparticles were sandwiched between graphene nanosheets, and the additional electrochemical contribution of the decorated CoS2 nanoparticles.

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.
