In catalysis research, EIS is employed to gain insights into the mechanisms of catalytic reactions and to evaluate the performance of catalysts. For instance, it can be used to study the kinetics of electrochemical reactions on the surface of catalysts, measure the efficiency of electrocatalysts, and understand the degradation mechanisms in fuel cells and batteries. By analyzing the impedance spectra, researchers can extract valuable parameters such as the charge transfer resistance, which is directly related to the catalytic activity.
