The Chalkboard: Relating Cyclic Voltammetry and Electrochemical Impedance Spectroscopy in a Mass Transport Controlled System

摘要

Cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) have become two of the most ubiquitous techniques in electrochemistry over the past few decades. While there have been many excellent reviews, textbooks, and introductory papers written regarding CV, the jump that most students undertake from CV to EIS has much less supporting literature to draw on. This is especially true in the cases of reversible mass transport controlled systems where the Warburg impedance may become a predominant feature. Thus, we have developed a logical framework with which to demonstrate the interweaving concepts found in both CV and EIS in a reversible mass transport controlled system such that it may be used as an effective teaching tool for those aspiring to apply both techniques in the study of electrochemical systems.
