Electrochemical study of Cu2O in aqueous and non-aqueous solvents using cyclic voltammetric technique
Author(s): Manisha Bhattacharya, Pintu B and SG Dixit
Abstract: Cyclic voltammetry investigations were conducted on Cu2O in water-sodium sulphite and dimethyl sulfoxide (DMSO) solutions. In the water-sodium sulphite system, pH variations influenced the shape and position of anodic and cathodic peaks, indicating the involvement of different copper species. The reversibility of Cu2O was confirmed, with successive scans revealing the transition of copper species between oxidation states. pH adjustments were found to impact peak potentials, suggesting potential for enhancing selectivity. In the DMSO system, initial cycles exhibited absence of anodic peaks followed by their emergence, accompanied by shifts in peak potentials and sharper cathodic humps. Scan reversal potentials influenced the appearance of anodic peaks, elucidating the oxidation of Cu2O to CuO and subsequent reduction processes. As cycles progressed, peak heights increased, indicating favored reduction of Cu+2 to Cu+1 and metallic copper. Overall, the electrochemical reaction of Cu2O proceeded via a two-electron process, with pH and concentration manipulation offering avenues for optimizing electrochemical properties.
