Abstract

The hydrogen and oxygen evolution reactions in the electrolysis of water were studied on Ni-Fe and Ni-Co co deposits, respectively, in 28% KOH solution at 60 deg C. The studies were carried out on micro and macro electrodes and the results compared to those obtained with conventional materials. In the HER is observed a significant improvement in the electrocatalytic activity which points out the Ni-Fe co deposits as good substitutes for the conventional mild steel electrodes. In contrast, the Ni-Co co deposits don`t present enhanced activity when compared to Ni electro deposits. However the higher mechanic resistance observed make its utilization attractive.
