Fig. 2.8 Free energy variation of oxygen at different potentials and low initial oxygen blanket
concentration (θ o ) reduction on Pt(111) plane

in the electrolyte, v is the viscosity, and ω is the rotational speed of the rotating disk.
Equation (2.5) is used to calculate the oxygen reduction limit current density.
On the rotating ring disk electrode, O 2 is reduced to an intermediate product on the
disk of the rotating electrode, and the intermediate product is thrown to the periphery
due to the centrifugal force. The mechanism of the oxygen reduction reaction is
