The electrocatalytic activity of the resulting composite Ni-Cu film was investigated toward the oxidation of carbohydrates using glucose as a model compound. The presence of copper oxyhydroxide species in deposited film imparts an extensive stabilization of the β/β crystallographic forms of the nickel oxyhydroxide under prolonged repetitive potential cycling in alkaline medium. ![]() The resulting deposited alloys appear uniform, smooth, adherent to the gold substrate, and homogeneous, independently of the electrochemical procedure adopted for the preparation ( i.e., potentiostatic or potentiodynamic conditions). The electrodeposited alloy film, with an average composition Ni:Cu of 0.67 ( i.e., was investigated by electrochemical, scanning electron microscopy, and X-ray photoelectron spectroscopy techniques. Setting up experiments, acquiring data points and performing data analysis to produce publication-ready graphs, can be done in a few mouse clicks. ![]() It is designed to answer demands of both experienced electrochemists and newcomers alike. A new and simple electrochemical procedure of anodic codeposition of nickel and copper oxide-hydroxide species on the gold electrode substrate from alkaline solutions is described. NOVA is the data acquisition and analysis software package for all the Autolab potentiostat/galvanostats.
