Metal-organic frameworks-derived honeycomb-like Co3O4/three-dimensional graphene networks/Ni foam hybrid as a binder-free electrode for supercapacitors
Honeycomb-like Co3O4/3DGN/NF hybrid was prepared by using the Co-based metal–organic frameworks as the precursor. The as-fabricated hybrid was applied as a binder-free electrode for supercapacitors. The electrode shows an excellent electrochemical performance.
