Fourier transformed large amplitude alternating current voltammetry: principles and applications

Research output: Contribution to journalArticleResearchpeer-review


In this review article, the basic principles of Fourier transformed large amplitude ac voltammetry (FTACV), as developed by the Monash Electrochemistry Group, are surveyed. Special attention is paid to the key features associated with the higher order harmonic components of FTACV that are not available in dc transient voltammetry, including (1) enhanced kinetic sensitivity; (2) rejection of background charging current and (3) insensitivity to homogenous catalysis coupled to electron transfer. Examples are then given to demonstrate the high sensitivity offered by FTACV in studies of surface-confined processes and electrode kinetic determinations, and the ability to extract thermodynamic information relevant to the electron transfer step and kinetic data for the coupled catalytic process separately under catalytic turnover conditions.
