Oxidation and reduction are complementary electron-transfer processes that underpin redox chemistry and many biological and industrial transformations. Oxidation is defined as the loss of electrons, an increase in oxidation state, or, in many covalent systems, gain of electronegative substituents (e.g., oxygen) or loss of electropositive ones (e.g., hydrogen). Reduction is the gain of electrons, a decrease in oxidation state, or the converse change in bonding pattern. In any redox reaction, electrons are conserved and transferred from a reductant (electron donor) to an oxidant (electron acceptor), often mediated by redox couples, half-reactions, and characterized quantitatively by standard reduction potentials.
Due to their considerable efficiency, catalysts made of just a few atoms show great promise in the field of water treatment. In a new study, researchers looked into how to optimize the performance of these catalysts and make ...
