Graphical abstractWe have successfully fabricated the thin Co3O4 nanosheet arrays on 3D porous graphene/nickel foam by a novel and facile strategy. The as-constructed thin Co3O4 nanosheet array electrode with a 3D hierarchically porous architecture shows the superior pseudocapacitive performance with a high specific capacitance of 2459Fg−1 after 2000 cycles at the current density of 8Ag−1.
