Abstract : The mechanism of oxygen reduction on the surface of gold electrodes was studied using a rotating disk electrode with a ring. In acid solution hydrogen peroxide is the product of the reduction. In alkaline solutions hydrogen peroxide is an intermediate during the reduction. By oxidation and reduction small areas on the gold surface become more active and reduce oxygen directly to water. (Author)
