| Abstract | Highly nanoporous nickel oxide electrodes were obtained by electrodeposition accompanied by hydrogen evolution reaction and the selective electrochemical dealloying of copper from Ni-(Cu) porous foam. The nanoporous nickel oxide electrodes consequently have numerous dendritic morphologies composed of nanopores with 20–30 nm diameters. The specific capacitances were 428 F g−1 for as-deposited Ni-(Cu) foam electrode and 1,305 F g−1 for nanoporous nickel-oxide electrode after dealloying process, respectively. This indicates increased surface area by dealloying process leads to innovative increase of specific capacitance. |
