Abstract
The copper nanocone (Cu-NC) array electrodes were successfully synthesized by metal sputtering on Al2O3/Al substrate with conical nanopores followed by electrodeposition of Cu. To fabricate the conical pores on aluminum substrate, repeated and alternating anodizations and pore widening treatments were performed. Each anodization step was conducted at 45 V in a 0.3 M oxalic acid solution at 9
