Reduced ZnCo2O4@NiMoO4·H2O heterostructure electrodes with modulating oxygen vacancies for enhanced aqueous asymmetric supercapacitors

In this work, to obtain electrode materials with exponentially enhanced performance, we first put forward a synergistic strategy to construct a core-shell reduced ZnCo2O4@NiMoO4·H2O heterostructure. This constructed nanostructure makes the utmost of reduced ZnCo2O4 nanowires and NiMoO4·H2O nanosheets, and the prepared electrodes exhibit highly stepped-up electrochemical performance. The reduced ZnCo2O4 electrode with moderate oxygen vacancies...
