Novel three-dimensional (3D) hierarchical Co3O4/CuO nanowire (NW) arrays on nickel foam composed of CuO NW stems and Co3O4 nanosheet branches are synthesized by combining a facile, scalable, and cost-effective thermal oxidation method with a simple but powerful chemical bath deposition followed by a...
