A mechanistic model is herein presented for the reduction of H2O2(aq) in aqueous electrolytes on a rotating disk electrode that considers the possible heterogeneous dismutation of H2O2(aq). A theoretical analysis of this model predicts Koutecky-Levich plots that deviate from linearity at high rotation rates depending on the relative values of the rates constants of the processes involved, in agreement with the behavior found for a variety of electrode materials.
