Voltammetry is a class of electrochemical techniques where the potential of an electrode is systematically varied while measuring the resulting current. This relationship between potential and current provides information about the electrochemical reactions occurring at the electrode surface. In a typical voltammetric experiment, a working electrode is subjected to a potential waveform, and the current flowing through the electrode is recorded as a function of this applied potential. The shape and magnitude of the resulting voltammogram, which is a plot of current versus potential, reveal the identity and concentration of electroactive species in the electrolyte solution. Different voltammetric techniques exist, each employing a specific potential waveform such as linear sweep voltammetry, cyclic voltammetry, or square wave voltammetry. These methods are widely used for quantitative analysis, determination of reaction mechanisms, and studying the properties of redox-active materials in various fields including chemistry, biology, and materials science. The sensitivity and versatility of voltammetry make it a powerful tool for electrochemical characterization.
