“…In particular, many articles have been devoted to the synthesis, microstructure, and properties of cobalt oxide nanoparticles due to their high potential as catalysts [1,2], gas sensors [3], and magnetic materials [4,5]. Cobalt oxides have been prepared by different procedures, e.g., the sol-gel process [6,7], hydrothermal synthesis [8], mechanochemical processing reactions [9], and combustion synthesis [10,11].…”

Cobalt oxides, CoO and Co3O4, were obtained from Co (II) acetate tetrahydrate. The thermal decomposition pathway of the starting product was followed by combining thermogravimetric analysis and in situ X-ray thermodiffraction. Under a nitrogen atmosphere, cobalt monoxide with Zn-blende and rocksalt polymorphs could be obtained almost as single phases at 330 and 400 °C, respectively. In addition to these oxides, a Co (II) oxyacetate, Co3O(CH3COO)4, was stabilized as an intermediate phase. Under an air atmosphere, Co3O4 (spinel structure type) was obtained as the only final product. The involved phases in this thermal decomposition process were characterized with scanning and transmission electron microscopy (SEM and TEM, respectively).

Cobalt ferrite/graphene nanocomposite materials were prepared by a one-pot hydrothermal method. Graphene oxide (GO) was synthesized by a modified Hummers method. The surface morphologies and structures of CoFe 2 O 4 /graphene nanocomposite materials were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), thermogravimetric analyzer (TGA), and fourier transform infrared spectroscopy (FTIR). SEM and TEM investigations unveiled that graphene sheets were uniformly well decorated by spherical cobalt ferrite nanoparticles (~ 3-6 nm). Electrochemical studies on CoFe 2 O 4 /graphene nanocomposite revealed the decline in the charge transfer resistance (~ 27 Ω), while on the other hand, higher corrosion current density (0.3837) and corrosion rates (0.00446) were observed. Cyclic voltammograms (CV) outcomes confirmed supercapacitor performance. The poor corrosion performance of the nanocomposite materials could be attributed to its higher conductivity.
