A Beginner’s Guide to Simulation of Electroanalytical Experiments using COMSOL Multiphysics®

Electroanalytical methods are fundamental in exploring the kinetics and mechanisms of electrochemical reactions, with widespread applications across the pharmaceutical, corrosion and metal industries, as well as in environmental laboratories. For analytical chemistry students, proficiency in both electroanalytical experiments and simulations is crucial. Simulations allow for the comparison with empirical data, thereby informing experimental design and elucidating reaction mechanisms. This guide caters to analytical chemistry students eager to master electroanalytical simulation using COMSOL Multiphysics. We show how relevant electrochemical equations and principles are implemented in COMSOL. In particular, we cover the simulation of steady-state current, cyclic voltammetry, and differential pulse voltammetry by utilizing the Transport of Diluted Species physics module of COMSOL.
