PREPARATION OF HIGH SURFACE-AREA NICKEL-OXIDE ELECTRODES FOR SYNTHESIS

A study of the electrodeposition of nickel onto copper and graphite is described; the objective was to prepare high surface area, i.e. microrough, but stable deposits which could be used as nickel oxide anodes in aqueous base. It is shown that such electrodes may be prepared by electrodeposition at a high current density (200 mA cm-2) from a Watts bath and that they give useful apparent current densities for a model synthetic reaction, the oxidation of ethanol to acetic acid. © 1979 Chapman and Hall Ltd.
