Magnetite ultrafine particles/porous reduced graphene oxide in situ grown onto Ni foam as a binder-free electrode for supercapacitors

Abstract

Here, we report a simple and green electrochemical route to deposition of Fe₃O₄ nanoparticle-porous reduced graphene oxide (p-rGO) nanocomposite onto nickel foam substrate, which is directly used as a binder-free charge storage electrode.
