Anodic and cathodic components of currents of quasireversible electrode reactions on rotating disk electrodes under steady state conditions

In a rotating disk electrode setup at constant potential, the current of a simple redox reaction becomes time-independent under steady-state conditions. This steady-state current can be expressed as a sum of two components, according to Butler-Volmer kinetics. While these components cannot be measu...

description In a rotating disk electrode setup at constant potential, the current of a simple redox reaction becomes time-independent under steady-state conditions. This steady-state current can be expressed as a sum of two components, according to Butler-Volmer kinetics. While these components cannot be measured experimentally, they can be calculated using simple formulae based on the formal potential of the electrode reaction, which can be determined from the potential of zero current on the steady-state current-potential curve. The components can then be used to measure the transfer coefficients of quasireversible electrode reactions.
