One-pot Hydrothermal Synthesis of 3D Flower-like RGO/Co3O4/Ni(OH)2 Composite Film on Nickel Foam for High-performance Supercapacitors

Protuberant 3D flower-like network structures of RGO/Co3O4/Ni(OH)2 nanocomposites, in-situ synthesized on nickel foam (NF) using a simple, green one-pot hydrothermal approach, exhibits excellent capacitive performance (10.24 F cm−2 at 11 mA cm−2, i.e., 2133.3 F g−1 at 2.3 A g−1).
