## What are electrochemical methods?

Electrochemical methods are experimental techniques that involve applying an electrical potential or current to an electrode immersed in an electrolyte solution (a liquid that can conduct electricity) and measuring the resulting electrical or chemical response. Electrochemical methods can be used to study the kinetics (rate) and thermodynamics (energy) of electrode reactions (reactions that occur at the interface between the electrode and the electrolyte), as well as the properties of the electrode surface (such as its structure, composition, charge distribution, adsorption behavior, etc.). Electrochemical methods can also be used to manipulate the electrode surface (such as by depositing or dissolving metals, forming films or layers, modifying its functionality or morphology, etc.) or to induce chemical reactions in the bulk solution (such as by generating radicals, oxidizing or reducing species, producing light or heat, etc.).

### Types of electrochemical methods

There are many types of electrochemical methods that can be classified based on different criteria such as the type of potential or current applied, the type of measurement performed, the type of electrode or cell used, the type of information obtained, etc. Here, we will briefly describe some of the most common types of electrochemical methods based on their principles and techniques.

#### Potential step methods

Potential step methods are electrochemical methods that involve applying a sudden change (step) in the potential of the working electrode (the electrode whose potential or current is controlled) and measuring the resulting current as a function of time. Potential step methods can be used to study the kinetics of fast electrode reactions, the diffusion of reactants or products in the solution, the capacitance of the electrode surface, etc. Some examples of potential step methods are chronopotentiometry (measuring the potential after a current step), chronocoulometry (measuring the charge after a potential step), chronoamperometry (measuring the current after a potential step), etc.

#### Potential sweep methods

Potential sweep methods are electrochemical methods that involve applying a linear or cyclic change (sweep) in the potential of the working electrode and measuring the resulting current as a function of potential. Potential sweep methods can be used to study the kinetics of slow or reversible electrode reactions, the thermodynamics of electrode reactions, the presence and concentration of electroactive species in the solution, etc. Some examples of potential sweep methods are linear sweep voltammetry (applying a linear potential sweep and measuring the current), cyclic voltammetry (applying a cyclic potential sweep and measuring the current), differential pulse voltammetry (applying a series of small potential pulses superimposed on a linear potential sweep and measuring the current), etc.

#### Polarography and pulse voltammetry

Polarography and pulse voltammetry are electrochemical methods that involve applying a series of discrete potential steps or pulses to a dropping mercury electrode (a special type of working electrode that consists of a capillary tube that periodically releases small drops of mercury) and measuring the resulting current as a function of potential. Polarography and pulse voltammetry can be used to study the kinetics and thermodynamics of irreversible or complex electrode reactions, the presence and concentration of trace elements or organic compounds in the solution, etc. Some examples of polarography and pulse voltammetry are classical polarography (applying a linear potential sweep to a dropping mercury electrode and measuring the current), differential pulse polarography (applying a series of small potential pulses superimposed on a linear potential sweep to a dropping mercury electrode and measuring the current), square wave voltammetry (applying a series of square wave potential pulses to a dropping mercury electrode or another type of working electrode and measuring the current), etc.

#### Controlled-current techniques

Controlled-current techniques are electrochemical methods that involve applying a constant or variable current to the working electrode and measuring the resulting potential as a function of time or current. Controlled-current techniques can be used to study the kinetics and thermodynamics of irreversible or complex electrode reactions, the diffusion of reactants or products in the solution, the properties of the electrode surface, etc. Some examples of controlled-current techniques are potentiostatic coulometry (applying a constant current to the working electrode until a certain amount of charge is passed and measuring the potential), galvanostatic coulometry (applying a constant current to the working electrode until a certain potential is reached and measuring the charge), potentiodynamic coulometry (applying a variable current to the working electrode and measuring the potential), galvanodynamic coulometry (applying a variable current to the working electrode and measuring the charge), etc.

#### Hydrodynamic methods

Hydrodynamic methods are electrochemical methods that involve applying an external force (such as gravity, centrifugation, rotation, vibration, etc.) to induce a flow or convection of the electrolyte solution near the working electrode and measuring the resulting current or potential as a function of time, potential, or rotation speed. Hydrodynamic methods can be used to study the kinetics and thermodynamics of fast or slow electrode reactions, the mass transfer coefficients of reactants or products in the solution, the effects of turbulence or mixing on the electrode process, etc. Some examples of hydrodynamic methods are rotating disk electrode (RDE) technique (applying a constant or variable potential or current to a disk-shaped working electrode that rotates at a constant or variable speed and measuring the current or potential), rotating ring-disk electrode (RRDE) technique (applying a constant or variable potential or current to a disk-shaped working electrode that rotates at a constant or variable speed and has a concentric ring-shaped counter electrode that collects some of the products generated at the disk and measuring the currents at both electrodes), etc.

#### Impedance methods

Impedance methods are electrochemical methods that involve applying a small sinusoidal potential or current to the working electrode and measuring the resulting current or potential as a function of frequency. Impedance methods can be used to study the resistance and capacitance of the electrode surface, the charge transfer kinetics of electrode reactions, the diffusion of reactants or products in the solution, the properties of electroactive layers or films on the electrode, etc. Some examples of impedance methods are electrochemical impedance spectroscopy (EIS) (applying a small sinusoidal potential to the working electrode and measuring the current as a function of frequency), electrochemical noise (EN) (measuring the fluctuations of potential or current at the working electrode without applying any external signal), etc.

#### Bulk electrolysis methods

Bulk electrolysis methods are electrochemical methods that involve applying a constant or variable potential or current to the working electrode for a long period of time and measuring the amount or concentration of reactants or products in the solution before and after the electrolysis. Bulk electrolysis methods can be used to study the stoichiometry and yield of electrode reactions, the formation and decomposition of intermediates or complexes, the effects of pH, temperature, additives, etc. on the electrode process, etc. Some examples of bulk electrolysis methods are coulometric titration (applying a constant current to the working electrode until a certain amount of charge is passed and measuring the change in concentration or pH of a titrant in the solution), controlled-potential coulometry (applying a constant potential to the working electrode until a certain amount of charge is passed and measuring the change in concentration or pH of a titrant in the solution), controlled-current coulometry (applying a constant current to the working electrode until a certain potential is reached and measuring the change in concentration or pH of a titrant in the solution), etc.

#### Spectroelectrochemistry and other coupled characterization methods

Spectroelectrochemistry and other coupled characterization methods are electrochemical methods that involve combining an electrochemical technique with another analytical technique to obtain complementary information about the electrode process. Spectroelectrochemistry and other coupled characterization methods can be used to study the structure, composition, orientation, bonding, electronic states, etc. of electroactive species on the electrode surface or in the solution, as well as their changes during the electrode process. Some examples of spectroelectrochemistry and other coupled characterization methods are infrared spectroelectrochemistry (combining an electrochemical technique with infrared spectroscopy), Raman spectroelectrochemistry (combining an electrochemical technique with Raman spectroscopy), UV-Vis spectroelectrochemistry (combining an electrochemical technique with UV-Vis spectroscopy), X-ray spectroelectrochemistry (combining an electrochemical technique with X-ray spectroscopy), scanning probe microscopy (SPM) electrochemistry (combining an electrochemical technique with scanning probe microscopy), etc.

#### Photoelectrochemistry and electrogenerated chemiluminescence

Photoelectrochemistry and electrogenerated chemiluminescence are electrochemical methods that involve applying light or generating light during an electrochemical process. Photoelectrochemistry and electrogenerated chemiluminescence can be used to study the effects of light on the electrode process, the generation of light by the electrode process, the properties of photoactive materials or devices, etc. Some examples of photoelectrochemistry and electrogenerated chemiluminescence are photoelectrocatalysis (using light to enhance the rate or selectivity of an electrocatalytic reaction), dye-sensitized solar cells (DSSCs) (using light to generate electricity from a dye-coated semiconductor electrode), electroluminescence (generating light by applying an electric field to a luminescent material), chemiluminescence (generating light by a chemical reaction), etc.
