Limiting currents, diffusion coefficients, and activation energy of oxygen diffusion in air-saturated 0.1M sulfuric acid at 5-75°
By Zembura, Zdzislaw; Kolny, Henryk
From Roczniki Chemii (1967), 41(9), 1629-32. Language: English, Database: CAPLUS
The limiting diffusion currents of the cathodic redn. of O dissolved in air-satd. 0.1 M H2SO4 at 5-75° were detd. by using the rotating-disk electrode. The diffusion coeffs. of O varied from (0.96 ± 0.03) × 10-6 at 5° to (3.91 ± 0.12) × 10-6 cm.2/sec. at 75°. The activation energy of O diffusion depended on temp. and was 6.1 and 2.4 kcal./mole at 15-25 and 50-75° temp. range, resp.



Parallel-successive stages of oxygen and hydrogen peroxide reactions. VII. Effect of chemisorbed oxygen on the electroreduction of molecular oxygen on palladium
By Tarasevich, M. R.; Vilinskaya, V. S.
From Elektrokhimiya (1973), 9(1), 98-101. Language: Russian, Database: CAPLUS
A mechanism of O electroredn. on Pd electrode was studied. It was dependent on the amt. of O chemisorbed during the previous anodic oxidn. of the Pd electrode in 0.1N H2SO4 and NaOH, resp. The amt. of chemisorbed O was varied in the anodic oxidn. at 2.0-2.5 V for 20-30 sec. Increasing the amt. of O chemisorbed, on account of formation of H2O mols., suppressed both the redn. of O directly to H2O and via H2O2 intermediate. The rate of the latter mechanism is less suppressed so that the redn. to H2O2 dominated after oxidn. at 1.9 V. The rate of further H2O2 transformation decreased at the same time. Occupation of Pd surface by the chemisorbed O makes adsorption of mol. O and the subsequent dissocn. difficult, the 4-electron mechanism is suppressed, and the redn. of mol. O proceeds via H2O2.

Electrochemical reduction of oxygen on carbon materials with different crystal structures
By Zagudaeva, N. M.; Vilinskaya, V. S.; Shteinberg, G. V.
From Elektrokhimiya (1982), 18(4), 541-4. Language: Russian, Database: CAPLUS
The electrochem. redn. was studied of O on isotropic and anisotropic pyrolytic C samples differing in their crystal structures; a ring-disk electrode method, in which the ring was platinized Pt was used. The expts. were conducted in H2SO4 and KOH, each 0.1N. Polarization curves were plotted.

Oxygen and hydrogen peroxide reactions in parallel-series. III. Oxygen and hydrogen peroxide reactions on a rhodium electrode
By Radyushkina, K. A.; Tarasevich, M. R.; Burshtein, R. Kh.
From Elektrokhimiya (1970), 6(9), 1352-5. Language: Russian, Database: CAPLUS
A study of the redn. mechanisms of O2 on a Rh ring-and-disk electrode in alk. solns. indicates that the process takes place both in 2- and 4-electron steps. The increase in the 4-electron part of the reaction in relation to that for Pt is apparently related to the increased affinity of Rh for O2 and consequently with the increase, on going from Pt to Rh, of the rate of dissocn. of chemisorbed O2.
Further conversion of H2O2, formed in parallel reaction, takes place via an electrochem. mechanism and, at an applied voltage >0.7 V, a catalytic delay process occurs although at a relatively small rate.
