Electrochemical CO reduction

Electrochemical CO reduction is an electrocatalysis method in which carbon monoxide is reduced at a copper cathode to value-added fuels and feedstocks, chiefly ethylene, ethanol, acetate, and methane.

Electrochemical CO2 capture with quinones

Electrochemical CO2 capture with quinones uses battery-like redox cells in which quinones bind CO2 when reduced and release it when oxidized, using electricity instead of heat.

Electrochemical CO2 reduction to formate

Electrochemical CO2 reduction to formate converts carbon dioxide into formate or formic acid at a cathode, a leading route for turning waste CO2 into value-added chemicals.

Electrochemical cross-coupling

Electrochemical cross-coupling forms carbon–carbon and carbon–heteroatom bonds using electrode-supplied electrons instead of stoichiometric chemical reagents, a field that has grown rapidly since the mid-2010s.

Electrochemical cross-electrophile coupling

Electrochemical cross-electrophile coupling (eXEC) is a carbon–carbon bond-forming reaction joining two electrophiles, such as organic halides, under nickel catalysis with reducing equivalents supplied by electricity instead of metal reductants.

Electrochemical dearomatization

Electrochemical dearomatization is a set of organic synthesis methods that use electrode electrons instead of chemical oxidants to convert planar aromatic rings into sp3-rich cyclic products.

Electrochemical difunctionalization

Electrochemical difunctionalization is a class of organic reactions that adds two functional groups across alkene or alkyne bonds using electrode-driven electric current instead of chemical oxidants.

Electrochemical flow chemistry

Electrochemical flow chemistry performs electrochemical reactions, where electrodes replace chemical oxidants and reductants, in a flowing reactor rather than a batch vessel, and is regarded as the best scale-up strategy for electrosynthesis.

Electrochemical fluorination

Electrochemical fluorination, also called the Simons process, replaces carbon-bonded hydrogen with fluorine by electrolysis in liquid anhydrous hydrogen fluoride, first commercialized by 3M in 1951.

Electrochemical hydrogenation

Electrochemical hydrogenation (ECH) is a method of adding hydrogen to unsaturated organic compounds in an electrochemical cell, where the cathode supplies electrons and water serves as the hydrogen source, avoiding compressed hydrogen gas.

Electrochemical impedance spectroscopy

Electrochemical impedance spectroscopy (EIS), also known as AC impedance spectroscopy, applies small sinusoidal voltages across many frequencies to separate processes like charge transfer, diffusion, and adsorption.

Electrochemical Kolbe-type couplings

Electrochemical Kolbe-type couplings are anodic decarboxylative reactions in which carboxylic acids are oxidized at an electrode to form carbon radicals that forge new carbon–carbon bonds.

Electrochemical mass spectrometry

Electrochemical mass spectrometry (EC-MS), including the DEMS variant, couples an electrochemical cell to a mass spectrometer to detect and quantify volatile electrode products and intermediates in real time.

Electrochemical methane oxidation

Electrochemical methane oxidation converts methane to partially oxidized products such as methanol at an electrode under mild conditions, aiming for selectivity against the competing oxygen evolution reaction.

Electrochemical nickel catalysis

Electrochemical nickel catalysis applies an electric current through electrodes to generate the active oxidation states of a nickel catalyst in organic synthesis, growing rapidly since about 2010.

Electrochemical nitrate reduction

Electrochemical nitrate reduction (NO3RR) is an electrocatalytic method that converts dissolved nitrate ions into ammonia or nitrogen gas, for ammonia synthesis and nitrate removal from water.

Electrochemical nitrogen reduction

Electrochemical nitrogen reduction (NRR) is an electrocatalytic method that converts atmospheric nitrogen into ammonia at an electrode, pursued as an alternative to the Haber–Bosch process.

Electrochemical organocatalysis

Electrochemical organocatalysis combines organocatalysis, catalysis by small metal-free organic molecules, with anodic or cathodic electron transfer, so an electrode replaces stoichiometric chemical oxidants or reductants in asymmetric synthesis.

Electrochemical oxidation

Electrochemical oxidation is a chemical reaction in which an atom or molecule loses electrons at the anode when current is passed, used in organic synthesis and water treatment.

Electrochemical oxidative coupling

Electrochemical oxidative coupling is a synthetic method that joins two organic substrates by anodic oxidation at an electrode, replacing stoichiometric chemical oxidants with electricity and releasing hydrogen at the cathode.

Electrochemical pH-swing CO2 capture with quinone electrodes

Electrochemical pH-swing CO2 capture with quinone electrodes is a carbon-capture method where electrochemically reduced and oxidized quinones shift the pH of a solution, absorbing CO2 at high pH and releasing it at low pH.

Electrochemical polymerization

Electrochemical polymerization, also called electropolymerization, is a synthesis method in which an electrode's applied potential grows polymer films, chiefly conducting polymers such as polypyrrole and PEDOT.

Electrochemical potential

The electrochemical potential is the partial molar Gibbs energy of a substance at a specified electric potential, combining chemical and electrical contributions and underlying the Nernst equation.

Electrochemical quartz crystal microbalance

The electrochemical quartz crystal microbalance (EQCM) combines a quartz crystal microbalance with an electrochemical cell to measure mass changes at an electrode surface while current and potential are recorded.

Electrochemical reduction of carbon dioxide

Electrochemical reduction of carbon dioxide, or carbon dioxide electrolysis, is an electrolysis process that converts CO2 into products such as carbon monoxide, formic acid, and ethylene.
