Fabrication of 3D HierarchicalSphericalHoneycomb-Like Nd₂O₃/Co₃O₄/Graphene/Nickel Foam Composite Electrode Material for High-Performance Supercapacitors.

ABSTRACT: A 3D hierarchical spherical honeycomb-like composite electrode materialof neodymium oxide (Nd₂O₃), cobalt tetraoxide (Co₃O₄), and reduced graphene oxide (rGO) on nickel foam (named as Nd₂O₃/Co₃O₄/rGO/NF) were successfully fabricated by combining the hydrothermal synthesis method and the annealing process. Nickel foam with a three-dimensional spatial structure was used as the growth substrate without the use of any adhesives. The Nd₂O₃/Co₃O₄/rGO/NF composite has outstanding electrochemical performance and can be used directly as an electrode material for supercapacitors (SCs). By taking advantage of the large specific surface area of the electrode material, it
