Cyclic voltammetry

Abstract

Cyclic voltammetry (CV) is perhaps the most versatile electroanalytical technique for the study of electroactive species. Its versatility combined with ease of measurement has resulted in extensive use of CV in the fields of electrochemistry, inorganic chemistry, organic chemistry, and biochemistry. Cyclic voltammetry is often the first experiment performed in an electrochemical study of a compound, a biological material, or an electrode surface. The effectiveness of CV results from its capability for rapidly observing the redox behavior over a wide potential range. The resulting voltammogram is analogous to a conventional spectrum in that it conveys information as a function of an energy scan.In spite of the wide usage enjoyed by CV, this technique is not generally well understood in comparison to other instrumental methods such as spectroscopy and chromatography.

“…(n = the number of exchanged electrons, A = electrode area (cm 2 ), D = diffusion coefficient (cm 2 s -1 ), C = bulk concentration (mol cm -3 ) of the electroactive species [29]), can be applied to the oxidation peak a and the reduction peak b. The peak current ratios, i pa,ox (peak a) /i pc,red (peak b) , is thus indicative of the amount of electrons involved in the oxidation process of peak a relative the reduction process of peak b.…”
