The role of the reduction reaction in corrosion needs to be emphasized. The example used above only considered oxygen reduction as the cathodic half-cell; however, there are many other reducing species (also kn
and the concepts of oxidation and reduction were extended to include them. In the 19th century the new field of electrochemistry further broadened the definition of the oxidation-reduction reaction. Investigators observed that the ferric ion (Fe 3+ ) could be formed from the ferrous ion (Fe 2+...

In a highly acidic melt, the reduction of molybdate ions (Mo in + 6 oxidation state) to Mo as + 4 is coupled to an irreversible chemical reaction whereby molybdenum dioxide precipitates. Molybdenum in oxidation state + 4 is reduced to Mo-(+2)-species which are immediately reoxidized to ...
I. Oxidation-Reduction Reactions: are chemical reactions that occur when electrons are transferred between reactants. Oxidation-reduction reactions (or redox reaction) are another type of chemical reaction in addition to the five we have already studied (synthesis, ...

Oxygen reduction reaction (ORR) kinetics have generated great interest due to their rate limiting role in fuel cells and metal-air batteries1,2,3,4. ORR kinetics have primarily been investigated computationally or through electrochemical measurements1,2,3, 5,6,7,8. Many experimental investigations...
The decrease in cross-section by corrosion in various environments has been emphasized and analyzed by Grünling et al. (1980). The influence of environmental effects due to high-temperature exposure before testing has been investigated in various superalloys, including IN 738 (Woodford, 1981). A...
Recently, coupling OER/UOR with heavy metals decomposition [38], electrochemical 4-Nitrophenol (4-NP) reduction reaction [39], electrochemical carbon dioxide reduction reaction (CO2RR), and electrochemical nitrogen reduction reaction (NRR) have also been investigated [40,41]. Furthermore, from the ...
Oxidation-Reduction Reaction (also redox reaction), a chemical reaction in which the oxidation numbers of the participating atoms change. Originally, at the end of the 18th century, when A. Lavoisier first proposed the oxygen theory of combustion, “oxidation” referred only to chemical reactions ...
