In heterogeneous electron transfer, an electron moves between a chemical species present in solution and the surface of a solid such as a semi-conducting material or an electrode. Theories addressing heterogeneous electron transfer have applications in electrochemistry and the design of solar cells.
An electron transport chain (ETC [1]) is a series of protein complexes and other molecules which transfer electrons from electron donors to electron acceptors via redox reactions (both reduction and oxidation occurring simultaneously) and couples this electron transfer with the transfer of protons (H + ions) across a membrane.
Photoinduced electron transfer (PET) is an excited state electron transfer process by which an excited electron is transferred from donor to acceptor. [ 1 ] [ 2 ] Due to PET a charge separation is generated, i.e. , redox reaction takes place in excited state (this phenomenon is not observed in Dexter electron transfer ).
Elementary steps like proton coupled electron transfer and the movement of electrons between an electrode and substrate are special to electrochemical processes. . Electrochemical mechanisms are important to all redox chemistry including corrosion, redox active photochemistry including photosynthesis, other biological systems often involving electron transport chains and other forms of ...
Outer sphere electron transfer can occur between chemical species that are identical except for their oxidation state. [4] This process is termed self-exchange. An example is the degenerate reaction between the tetrahedral ions permanganate and manganate:
A Proton-coupled electron transfer (PCET) is a chemical reaction that involves the transfer of electrons and protons from one atom to another. The term was originally coined for single proton, single electron processes that are concerted, [1] but the definition has relaxed to include many related processes.
SYDNEY (Reuters) -The remaining five members of the "Bali Nine" Australian drug ring have returned from Indonesia after diplomatic efforts between the countries this month to strike a repatriation ...
Inner sphere electron transfer (IS ET) or bonded electron transfer [1] is a redox chemical reaction that proceeds via a covalent linkage—a strong electronic interaction—between the oxidant and the reductant reactants. In inner sphere electron transfer, a ligand bridges the two metal redox centers during the electron transfer event. Inner ...
