INTERACTION OF HYDROGEN AND OXYGEN WITH CONTINUOUS OR GRANULAR FILMS OF PALLADIUM.

Desorption and conductometric methods have been used in establishing the existence of three species of adsorbed hydrogen on continuous Pd films and two species of adsorbed hydrogen on continuous Pd films and two species on Pd films with a granular structure. Preoxidation of the surface of the continuous films does not affect the rate or kinetic order of hydrogen sorption; oxidation/reduction treatment changes these parameters, but the magnitude of E//d//e//s of hydrogen remains unchanged. Preoxidation of granular films increases E//d//e//s of the H delta species and increases E//d//e//s of the O//2 delta species.
