Influence of surface phenomena on the impedance response of a rotating disk electrode

Abstract

The objective of this work was to explore the role of surface blocking on the impedance response associated with reduction of ferricyanide on a Pt rotating disk electrode. The analysis took into account the possible role of non-uniform current distribution on the impedance response. The results suggest that the time-dependent change to the Pt surface contributes to both a decrease of rate constant that hinders electrode kinetics and a blocking of the electrode surface that hinders mass transfer.
