Electrochemical properties of anodized copper hydroxide nanostructures

Here, we report room temperature growth of one-dimensional copper hydroxide, Cu(OH)2 nanostructures viz., nanoneedles (NNs), nanoleafs (NLs) and nanorods (NRs) from NaOH, LiOH and NaOH+ LiOH aqueous electrolyte solutions, respectively, employing a simple and cost-effective chemical anodization process. Structural elucidation and morphological evolution studies are elaborated thoroughly. Morphology inspired evolution of specific capacitance is estimated using cyclic-voltammogram and discharge measurements wherein, due to a relatively higher total charges and the least charge transfer resistance, in electrode with NRs morphology paved remarkable electrochemical performance compared to electrodes of NNs and NLs morphologies.
