Co3O4 nanomaterials are grown in situ on nickel foam by a facile two-step method, and their electrochemical properties for supercapacitors and electrochemical H2 production are systematically investigated. As an electrode material for supercapacitors, the Co3O4/NF nanomaterials have a specific capacitance of 4705 mF/cm2 at a current density of 2.5 mA/cm2 in 6 M KOH solution with good cycling stability. The asymmetric supercapacitor assembled with Co3O4/NF (positive) and activated carbon (negative) exhibits high energy storage capacity (2023 mF/...
