文摘
- •
Two types of hierarchical nanostructures were constructed using NiCo2O4 scaffolds.
- •
Areal capacitance of 7.29 F cm−2 is obtained for NiCo2O4-UNSA@NiMoO4 electrodes.
- •
The UNSA scaffold can provide more efficient electron transport channels.
- •
The NiCo2O4-UNSA@NiMoO4 electrodes show high rate capability (84.1% at 60 mA cm−2).
