Web19 Jan 2024 · Description The ability of the technique of large-amplitude Fourier transformed (FT) ac voltammetry to facilitate the quantitative evaluation of electrode processes involving electron transfer and catalytically coupled chemical reactions has been evaluated. WebAC voltammetry is an extension of classical linear sweepelectrochemical techniquessuch as cyclic voltammetry(CV) [1]. Analogous to CV, in AC voltammetry the mean DC potential V is imposed potentiostatically at arbitrary values that usually are different fromthe equilibrium value.
