REVERSIBLE OXYGEN ELECTRODES.
Abstract
A method for determining the role of H2O2 in oxygen reduction was developed. Preliminary results indicate that H2O2 is a true intermediate in KOH solution and is a product of a parallel reaction in H2SO4 solution. The catalytic activity for the oxygen reduction reaction is shown to be critically dependent on the electrode material, on the pretreatment of electrode, and, to some extent, on the purification of the system. In the purified system and with the pretreatment of the electrodes which leads to the oxide free electrode surface, different electrode materials (with different d-character, lattice distances, work function, bond energy metaloxygen...) are responsible for differences in observed catalytic activity.
