Cyclic Voltammetry

An example of a potentiodynamic electrochemical measurement is cyclic voltammetry (CV). The working electrode potential is scaled linearly against time in a cyclic voltammetry experiment. Contrary to linear sweep voltammetry, the working electrode's potential ramps in the opposite direction to return to the initial potential when the set potential is attained in a CV experiment. These potential-ramping cycles can be performed as many as necessary. The cyclic voltammogram trace is obtained by plotting the current at the working electrode vs the applied voltage (i.e., the potential of the working electrode). The electrochemical characteristics of an analyte in solution or of a molecule adsorbed onto the electrode are often studied using cyclic voltammetry. In several chemical fields, cyclic voltammetry (CV) has grown to be a significant and popular electroanalytical method. It is frequently employed to research various redox processes, as well as to ascertain the reversibility of a reaction, the stability of reaction products, the existence of redox reaction intermediates, and electron transfer kinetics. It can be applied to the electrochemical deposition of thin films or to identify the ideal range of reduction potentials for the ions in the electrolyte for electrochemical deposition. In addition, CV may be used to ascertain a system's electron stoichiometry, an analyte's diffusion coefficient, and an analyte's formal reduction potential, which can be utilised to identify an analyte.
