摘要

•Cu2O/NiO/copper foil has been successfully synthesized by dealloying a copper foil coated with Zn-Cu-Ni alloy films.•The resultant Cu2O/NiO possesses scalable nanosphere structure.•The Cu2O/NiO with nanosphere structure shows high specific capacitance (2255.5 mF/cm2) and excellent cycling stability (94.5% after 5000 cycles).
