•The Co3O4@MoO2 hybrid is fabricated via hydrothermal and electrodeposition method.•The Co3O4@MoO2 nanosheets arrays is composed of holey structure.•The Co3O4@MoO2 nanosheets displays excellent electrochemical property.
Uniform Co3O4@MoO2 nanosheet arrays is fabricated through hydrothermal and electrodeposition method by virtue of the chemical-etching method. The electrochemical measurements show that the specific capacitance of 600 F g−1 at a scan rate of 2 mV s−1 for the Co3O4@MoO2 hybrid is higher than both pristine MoO2 and Co3O4. Moreover, the hybrid electrode with low resistance displays good cyclic stability of 83% retention after 1000-cycle charge/discharge. These results indicate that the as-prepared Co3O4@MoO2 hybrid is a potential candidate used as electrode material in supercapacitors.
