CHARACTERIZATION OF ELECTROLESS NI-MO-P SNO2/TI ELECTRODES FOR OXYGENEVOLUTION IN ALKALINE-SOLUTION/

Ni-Mo-P alloy electrodes, prepared by electroless plating, were charac terized for application to oxygen evolution. The rate constants were e stimated for oxygen evolution on electrodes prepared at various Mo-com plex concentrations. The surface area and the crystallinity increase w ith increasing Mo content. The electrochemical characteristics of the electrodes were identified in relation to morphology and the structure of the surface. The results show that the electroless Ni-Mo-P electro de prepared at a Mo-complex concentration of 0.01 M provided the best electrocatalytic activity for oxygen evolution.
