- Abstract
We designed and fabricated hierarchical CoO@MnO nanoarrays directly grown on nickel foam by hydrothermal and calcination methods. After the investigation of growth mechanism, we found that the deposition of MnO was based on the self-decomposition of KMnO and the reducibility of CoO during the hydrothermal process. Thanks to the hierarchical structure, the obtained electrode exhibited excellent capacitive performance in supercapacitor. It delivered 21.72 F cm at a current density of 5 mA cm and retained ~94 % capacitance of initial value after 5000 cycles.
