Abstract
A general mathematical model is presented for studying the kinetics of oxygen reduction at a rotating disk electrode under steady state potentiostatic conditions. The model includes homogeneous reactions in the solution as well as heterogeneous non-charge-transfer reactions at the electrode surface. At given values of the applied potential, the model can be used to predict the net and partial current densities, the ohmic potential drop, and the concentration and potential profiles within the solution near a rotating disk electrode. The model is used to simulate the electrochemical reduction of oxygen at a rotating disk electrode under various conditions. Parameter estimation procedures based on nonlinear least squares are developed and combined with the model to provide estimates of the kinetic parameters and to elucidate the kinetics O₂ reduction at carbon and silver electrodes.
