Thin-Film Modified Rotating Disk Electrodes: Models of Electron-Transfer Kinetics for Passive and Electroactive Films

Abstract:
This work explores the influence of both passive and electroactive thin films upon the steady-state voltammetric response of a rotating disk electrode, proposing simple physical and algebraic models. In both cases, it is clearly evidenced how the alteration of the mass-transport regime adjacent to the electrochemical interface leads to an apparent change in the electron-transfer kinetics. These results are of great significance because of the wide adoption of the rotating disk electrode technique for studying new electrocatalytic materials.
