TL;DR: In this article, the effect of the diffuse double layer upon the reduction rates of Eu3+ and Cr3+ at mercury electrodes in various sodium and lanthanum perchlorate supporting electrolytes have been studied over as large a potential range as possible by using both chronocoulometry and d.c.H. polarography.

TL;DR: The experimental results are in excellent agreement with predictions from finite-element simulations coupling the governing equations for ion transport, electric fields, and the redox reactions.
Abstract: Ion transport near an electrically charged electrolyte/electrode interface is a fundamental electrochemical phenomenon that is important in many electrochemical energy systems. We investigated this phenomenon using lithographically fabricated thin-layer electrochemical cells comprising two Pt planar electrodes separated by an electrolyte of nanometer thickness (50–200 nm). By exploiting redox cycling amplification, we observed the influence of the electric double layer on transport of a charged redox couple within the confined electrolyte. Nonclassical steady-state peak shaped voltammograms for redox cycling of the ferrocenylmethyltrimethylammonium redox couple (FcTMA+/2+) at low concentrations of supporting electrolyte (≤10 mM) results from electrostatic interactions between the redox ions and the charged Pt electrodes. This behavior contrasts to sigmoidal voltammograms with a diffusion-limited plateau observed in the same electrochemical cells in the presence of sufficient electrolyte to screen the elec...

TL;DR: In this paper, a rotating GCE was found to be a suitable electrode for anodic stripping voltammetry of submicro amounts of metal ions, and the peak current and peak potential were obtained corresponding to the anodic dissolution of silver and copper in acidic, neutral and alkaline media.
