TL;DR: In this article, it was shown that the electrical double-layer at a solid electrode does not in general behave as a pure capacitance but rather as an impedance displaying a frequency-independent phase angle different from 90°.

TL;DR: In this paper, a critical study is made of the mathematics needed to describe the current response towards a potential step perturbation of an electrode at which phase formation takes place by the process of nucleation and diffusion-controlled hemispherical growth.

TL;DR: In this paper, the reduction of Zn(II) has been studied by means of the faradaic impedance method in wide potential and frequency ranges and at varied water activity, and the results obtained could be quantitatively explained on the assumption of a mechanism including at least the following consecutive steps: 1 (1) fast partial dehydration of the electroactive species; 2 (2) fast transport from the solution into the double layer; 3 (3) slow transfer of the first electron; 4 (4) a fast second partial dehydration step; 5 (5) slow transferred of the second

TL;DR: In this paper, the reduction of H+ from 1 M FICiO, and 1 IV NaCIO, solurions at polycrystalline and single crystal faces of very pure gold electrode, was studied by determining the forward rate constant kr as a funcrion of porential and of H' concentration.

TL;DR: In this paper, the authors report a protocol for evaluating the activity, stability, and Faradaic efficiency of electrodeposited oxygen-evolving electrocatalysts for water oxidation.
Abstract: Objective evaluation of the activity of electrocatalysts for water oxidation is of fundamental importance for the development of promising energy conversion technologies including integrated solar water-splitting devices, water electrolyzers, and Li-air batteries. However, current methods employed to evaluate oxygen-evolving catalysts are not standardized, making it difficult to compare the activity and stability of these materials. We report a protocol for evaluating the activity, stability, and Faradaic efficiency of electrodeposited oxygen-evolving electrocatalysts. In particular, we focus on methods for determining electrochemically active surface area and measuring electrocatalytic activity and stability under conditions relevant to an integrated solar water-splitting device. Our primary figure of merit is the overpotential required to achieve a current density of 10 mA cm–2 per geometric area, approximately the current density expected for a 10% efficient solar-to-fuels conversion device.

TL;DR: In this paper, the authors provide guidelines for experimental design, discuss the relevance of accuracy contour plots to wiring and instrumentation selection, and emphasize the importance of the Kramers-Kronig relations to data validation and analysis.
Abstract: Electrochemical impedance spectroscopy (EIS) is a powerful tool to investigate properties of materials and electrode reactions. This Primer provides a guide to the use of EIS with a comparison to other electrochemical techniques. The analysis of impedance data for reduction of ferricyanide in a KCl supporting electrolyte is used to demonstrate the error structure for impedance measurements, the use of measurement and process models, as well as the sensitivity of impedance to the evolution of electrode properties. This Primer provides guidelines for experimental design, discusses the relevance of accuracy contour plots to wiring and instrumentation selection, and emphasizes the importance of the Kramers-Kronig relations to data validation and analysis. Applications of EIS to battery performance, metal and alloy corrosion, and electrochemical biosensors are highlighted. Electrochemical impedance measurements depend on both the mechanism under investigation and extrinsic parameters, such as the electrode geometry. Experimental complications are discussed, including the influence of nonstationary behaviour at low frequencies and the need for reference electrodes. Finally, emerging trends in experimental and interpretation approaches are also described.
