Abstract: In this study, Ni-ZrO_2 and Ni-WC composite electrodes were prepared with the technique of composite electroplating, and used in the cathodic reduction reaction of H~+ in acid solution. The electrocatalytic properties and true surface area of the electrodes were determined by electrochemical and physical methods. It was found that the composite electrods had higher catalytic activity than pure Ni plated electrode for reduction reaction of H~+. The effect of content of the particles in the composite electrodes on the electrocatalytic property of the electrodes was discussed. Our results suggest that there is a possibility of preparing various new types composite electrode with electrocatalytic activities for certain redoxreaction system through the technique of composite electroplating by selecting proper materials.
