Cyclic Voltammetry

A kind of electrochemical measurement called Cyclic Voltammetry (CV) uses potentiodynamics. An experiment using cyclic voltammetry ramps the voltage of the working electrode linearly against time. The working electrode's potential ramps in the opposite direction to return to the beginning potential in a CV experiment, unlike in linear sweep voltammetry, after the set potential is attained. As many times as necessary, these potential ramping cycles can be performed. The cyclic voltammogram trace is obtained by plotting the current at the working electrode against the applied voltage (i.e., the potential of the working electrode). In most cases, cyclic voltammetry is used to examine the electrochemical characteristics of an analyte in solution or of a molecule that has been adsorbed onto the electrode. In various branches of chemistry, the electroanalytical method known as cyclic voltammetry (CV) has grown in significance and popularity. It is frequently employed to investigate a number of redox processes, as well as to ascertain the reversibility of a reaction, the existence of intermediates in redox reactions, the stability of reaction products, and the kinetics of electron transfer. It can be employed for the electrochemical deposition of thin films or for identifying the appropriate reduction potential range of the ions present in the electrolyte for electrochemical deposition. The formal reduction potential of an analyte and the diffusion coefficient of an analyte, which may be employed as identification tools, can also be determined using CV.
