Electrodes of rationally designed composite nanostructures can offer many opportunities for the enhanced performance in electrochemical energy storage. This paper attempts to illustrate the design and production of NiMoO4/polypyrrole core–shell nanostructures on nickel foam to be used in supercapacitor via a facile hydrothermal and electrodeposition process. It has been verified that this novel nanoscale morphology has outstanding capacitive performances. While employed as electrodes in supercapacitors, the composite nanostructures showed remarkable electrochemical performances with a great areal capacitance (3.2[Formula: see text]F/cm2 at a current density of 5[Formula: see text]mA/cm2), and a significant cycle stability (80% capacitance retention after 1000 cycles). The above results reveal that the composite nanostructures may be a likely electrode material for high-performance electrochemical capacitors.

Abstract Supercapacitive properties of Co/ZnCo oxide composite with a core-shell nanostructure (Co3O4/ZnCo2O4) prepared directly onto a nickel foam substrate by a two-step hydrothermal method were investigated. The synthesized core-shell structure consisted of some ~40-100 nm in thick flaky ZnCo2O4 deposits coated onto the surface of Co3O4 nanorods measuring ~150 nm in diameter. The specific capacitance value of the Co3O4/ZnCo2O4 core-shell nanostructure synthesized by hydrothermal at 130°C for a ZnCo2O4 deposition time of 2 h can attain 1804 F/g at a scan rate of 5 mV/s. Furthermore, the core-shell structured electrode still exhibited a relatively good capacitance retention of more than 93% after 3000 CV cycles due to the superior structural support of Co3O4 scaffolds. The Co3O4/ZnCo2O4 core-shell structure exhibits excellent electrochemical performances and, as such, is one of the more promising active materials in pseudocapacitor applications.
