Fourier transformed large amplitude square-wave voltammetry as an alternative to impedance spectroscopy: Evaluation of resistance, capacitance and electrode kinetic effects via an heuristic approach

Abstract:

A detailed simulation of Fourier transformed large amplitude square-wave voltammetry is presented in the frequency domain for the process Red ⇌ Ox + e-. The simulation takes into account the influence of the electrode kinetics (Butler-Volmer model), uncompensated resistance (R u) and double layer capacitance (Cdl). Of particular significance is the prediction that the even harmonic responses are only detected in the presence of quasi-reversibility or uncompensated resistance, and also are ess...
