STUDIES OF HYDROGEN AND OXYGEN EVOLUTION AND THE INFLUENCE OF ABSORBED SUBSTANCES

Abstract

This investigation has been concerned with hydrogen and oxygen evolution at electrodes and the influence of adsorbed substances. In this report AC measurements of the interface impedance prove to be suitable for studying adsorption phenomena on porous electrodes like platinated platinum and sintered nickel material. The impedance on platinum electrodes was evaluated for 8N H2SO4 and IN KOH solutions. Further investigations dealt with inhibition problems on highly activated porous nickel electrodes. Several alcohols were used as additives to IN KOH. The applicability of the potentiostatic method of applying triangular voltages was examined on bright nickel electrodes. The electrolytes 8N H2SO4 in IN KOH in general were stirred with purified nitrogen. The applicability of the potentiostatic method of triangular voltages to show the influence of inhibitors by applying the principle of Wagner-Traut was examined.
