Preparation and modification of hydrous thick cobalt oxide layers : Voltammetric characteristics of rough Co<sub>3</sub>O<sub>4</sub>-spinel-type electrodes

The application of a periodic perturbing potential to a cobalt electrode immersed in alkaline solutions at room temperature allows accumulation of a hydrous cobalt hydroxide overlayer which becomes a precursor to the production of a rough Co<sub>3</sub>O<sub>4</sub> spinel fi...
