We report a facile and controllable strategy for the fabrication of three-dimensional (3D) ZnCo2O4/NiO core/shell nanowire arrays (ZCO/NiO NWs) on nickel (Ni) foam substrates by a simple, cost-effective, two-step, solution-based method. Ultra-thin NiO nanosheets are revealed to grow uniformly on the porous ZnCo2O4 nanowires with many interparticle mesopores, resulting in the formation of 3D core/shell nanowire arrays with hierarchical architecture. In comparison with the pristine ZnCo2O4…
