ANODIC OXIDATION OF HYDROGEN ON IRON AND PLATINUM IN SODIUM HYDROXIDE SOLUTION

Abstract

In a rigorously controlled high-purity closed system, the electrochemical behavior of Fe and Pt electrodes for the hydrogen oxidation reaction showed marked differences in both the active and passive regions. The catalytic behavior of the two metals reflects the differences in metallic properties and anion adsorption. Iron was found to be a far better catalyst with a much less pronounced passive region. Iron corrosion was insignificant. Small amounts of platinum on iron strongly retarded hydrogen oxidation. Significant Pt dissolution and deposition on the iron working electrode was not found.
