from the slopes of Koutecky-Levich plots using the following equation:
1/jD=1/jk + 1/ Bω1/2
where jk is the kinetic current in amperes at a constant potential, ω is the electrode rotating
speed in rpm, and B, the reciprocal of the slope, which was determined from the slope of
Koutecky-Levich plots based on Levich equation as followed:
B=0.2 nFAv–1/6CO2DO2
2/3
where n is the number of electrons transferred per oxygen molecule, F is the Faraday constant
(96485 C mol-1), DO2 is the diffusion coefficient of O2 in 0.1 M KOH (1.9×10-5 cm s-1), v is the
kinetic viscosity, and CO2 is the concentration of O2 (1.2×10-3 mol L-1). The constant 0.2 is adopted
when the rotating speed is in rpm.
