Theory of the voltammetric response of electrodes of submicron dimensions. Violation of electroneutrality in the presence of excess supporting electrolyte

The steady-state voltammetric behavior of spherical electrodes of nanometer dimensions is computed by numerical solution of the Nernst-Planck and Poisson equations. The results are discussed in terms of a recent report of unusually large heterogeneous rate constants obtained by steady-state voltamet...

Zusammenfassung:	The steady-state voltammetric behavior of spherical electrodes of nanometer dimensions is computed by numerical solution of the Nernst-Planck and Poisson equations. The results are discussed in terms of a recent report of unusually large heterogeneous rate constants obtained by steady-state voltametry at electrodes of nanometer dimensions.
