Abstract
The electrolytic decomposition effect of particles on electrochemical phenomena at the Pt/10−3 M aqueous solution interface has been studied using voltammetric, time‐based, and electrochemical‐impedance techniques. The observed anodic decomposition effect of the particles on electrochemical phenomena was significant within the positive potential range (0 to 1.0 V vs. SCE). On the other hand, the cathodic decomposition effect of the particles was negligible in the negative potential range (0 to −1.0 V vs. SCE). The particles act as current activators or mediators during the anodic process and act as charge screens during the cathodic process. The solution resistance and related total impedance were increased due to the presence of the particles. The anodic decomposition of the particles can be used to increase the hydrogen evolution at the counterelectrode.Keywords
