A facile one-step route to RGO/Ni3S2 for high-performance supercapacitors

- A uniform 3D nest-like nanostructure of RGO/Ni3S2 nanocomposite on Ni foam, in-situ synthesized using a simple, green one-pot hydrothermal approach, exhibits superior capacitive performance (7440 mF cm−2 at 10 mA cm−2, i.e., 2188.8 F g−1 at 2.9 A g−1 and 1016 F g−1 at 29.0 A g−1)..
- RGO/Ni3S2/NF composite was in-situ synthesized through a one-step hydrothermal process.
- No other reagent except Ni foam, GO and S powder was added.
- RGO/Ni3S2, RGO/Ni(OH)2, and RGO/Ni3S2/Ni(OH)2 can be controllably synthesized.
- As-prepared RGO/Ni3S2/NF nanocomposite exhibits high capability and cyclability.
