Abstract

A novel strategy to prepare hierarchical mesoporous ZnCo₂O₄ nanosheets, decorated on a reduced graphene oxide/nickel foam template, was constructed. This unique nanostructure electrode, consisting of mesopores/micropores for pseudocapacitors, showed high capacitance, excellent cycling performance and good rate capability.
