Synergistic interaction between embedded Co₃O₄ nanowires and graphene papers for high performance capacitor electrodes

Abstract

nanowire composite films were successfully synthesized using a simple, three-step treatment, and the effect of the Co 3 O 4 nanowire content on the electrochemical properties of the composite films was studied. The one-dimensional Co 3 O 4 nanowires were homogeneously embedded and dispersed between prepared graphene papers, forming a layered graphene/Co 3 O 4 nanowire hybrid structure. These composite films exhibited better electrochemical properties than previously reported ones, such as graphene/CNT, where carbon spheres existed in the graphene composites, which were fabricated using the same method but without the Co 3 O 4 nanowires. The addition of a small amount of

Facile Synthesis and Characterization of MOF‐Derived Porous Co3O4 Composite for Oxygen Evolution Reaction

“…The O 1s peak showed in Figure b corresponds to mental‐oxygen bonds. The bingding energy of 528.9 eV, 529.3 eV and 530.4 eV being attributed to the lattice oxygen (O L ), oxygen vacancy (O V ) and chemisorbed oxygen (O C ), respectively …”

Reduced Graphene Oxide-Supported Co3O4 Nanocomposite Bifunctional Electrocatalysts for Glucose–Oxygen Fuel Cells

“…32 Co 3 O 4 showed insignificant weight loss until 900 °C. 33 The TGA plot for the rGO−Co 3 O 4 (10 wt % GO) nanocomposite disclosed high thermal stability and showed a typical weight loss for the decomposition of surface oxygen-containing functional groups between 200 and 320 °C. The 10 wt % loss between 320 and 450 °C was attributed to the removal of rGO from the nanocomposites.…”
