Cyclic Voltammetry Part 2: Surface Adsorption, Electric Double Layer, and Diffusion Layer

This paper “Part 2: Surface Adsorption, Electric Double Layer, and Diffusion Layer” is the applicational part a continuation of 1: Fundamentals” (https://doi.org/10.5796/electrochemistry.22-66082). explains principles cyclic voltammetry on adsorption, electric double layer, diffusion layer with microelectrodes. Moreover, recent trends, such as polymer electrolyte fuel cells (PEFCs), capacitors (EDLCs), sensors, are highlighted. The relationship between electrochemical surface area (ECSA) quantity estimated basis voltammograms explained in chapter where adsorption hydrogen carbon monoxide Pt discussed. following introduces pseudo-capacitance activated carbon, which exhibits characteristic capacitor-like behavior, Faradaic current flow surface. Finally, an explanation concerning effect diffusion-limiting currents two types microelectrodes practical case enzyme sensing using microelectrode included.
