A rotating disk electrode was used to examine the steady state kinetics of O 2 reduction at oxide free Pt in alkaline solutions of various pH's. Two linear V -log i regions are observed. At low current densities, the ∂V/∂ log i slope is close to

A rotating platinum disk electrode was used to study oxygen reduction over the entire pH range and to compare the kinetics in acid and alkaline solutions. In both solutions two Tafel regions are confirmed. At low cd's ∂V/∂ln i = −RT/F and at hi

The apparent enthalpies of activation, ΔH*a, for O2 reduction at Pt electrodes are determined in acid solutions of different pH. In the high current density region, characterized by a Tafel slope close to − 120 mV, ΔH*a,h is lower than ΔH*a,l in

Oxygen reducton (OR) at Pt electrodes in aqueous HClO4 solution (pH = 1.9) is examined at temperature from 5 to 45°C. At all temperatures, two distinct Elogi regions are observed. At low current densities (cd), the Tafel slopes are close to −2.

A special technique was developed to observe the phenomena occurring at very short time intervals after immersion of an electrode into the solution of more electropositive ions. A gun-like arrangement driven by gunpowder gave the electrode a consider
