“…The two peaks assigned to cobalt oxides centered at 780.8 and 795.9 eV can correspond to Co 2p3/2 and Co 2p1/2 [44]. The two distinct peaks of Co 2p3/2 were visibly located at 780.8 and 782.3 eV as attributed to the Co 3+ 2p3/2 and Co 2+ 2p3/2 configurations, respectively [49,50]. And the other spin orbit component (2p1/2) can be categorized into two peaks at 795.8 and 797.4 eV [49,50].…”

Carbon sphere (CS)@ZnO core-shell nanocomposites were successfully prepared through facile low-temperature water-bath method without annealing treatment. The morphology and the microstructure of samples were characterized by transition electron microscopy (TEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS), respectively. ZnO nanoparticles with several nanometers in size decorated on the surface of the carbon sphere and formed a core-shell structure. Electrochemical performances of the CS@ZnO core-shell nanocomposites electrodes were investigated by cyclic voltammetry (CV) and galvanostatic charge/discharge (GDC). The CS@ZnO core-shell nanocomposite electrodes exhibit much larger specific capacitance and cycling stability is improved significantly compared with pure ZnO electrode. The CS@ZnO core-shell nanocomposite with mole ratio of 1:1 achieves a specific capacitance of 630 F g−1 at the current density of 2 A g−1. Present work might provide a new route for fabricating carbon sphere and transition metal oxides composite materials as electrodes for the application in supercapacitors.

“…FeCo 2 O 4 can be considered as partial replacement of the Co 3 O 4 , where Fe atom replaces the Co of Co 3 O 4 without any changes in structure. The introduced metal atom can bring more redox reactions to enhance the electrochemical performance contrasted with Co 3 O 4 . It also can explain the promoted electrochemical performances between two‐metal TMOs and single‐metal TMOs.…”

Summary One‐step hydrothermal reaction has successfully been used to prepared three‐dimensional hierarchitecture Co2(OH)3Cl@FeCo2O4 composite without any annealing treatment. The samples are investigated to confirm the crystal structure, elemental composition, morphology structure and electrochemical performance. The results show the sample has a three‐dimensional hierarchitecture that nanoblocks are assembled with nanoparticles. And the specific surface area is 87.5 m2 g−1 and the total pore volume is 0.17 cm3 g−1. Meanwhile, the composite shows a high specific capacitance of 1110.0 F·g−1 at 1 A·g−1 and great cycling stability with 98.8% capacitance retention after 3000 cycles. To evaluate the electrochemical performances, the results are used to compare with the Co2(OH)3Cl and FeCo2O4 nanomaterials, indicating a higher capacitance and longer cycle stability shown by the as‐synthesized sample. The as‐synthesized Co2(OH)3Cl@FeCo2O4 composite has an outstanding electrochemical performance, predicting an enormous potential and promising future as a novel electrode material applied in supercapacitor.
