Continuous-flow electrosynthesis of ammonia by nitrogen reduction and hydrogen oxidation

Science, 2023
Ammonia is a critical component in fertilizers, pharmaceuticals, and fine chemicals and is an ideal, carbon-free fuel. Recently, lithium-mediated nitrogen reduction has proven to be a promising route for electrochemical ammonia synthesis at ambient ...

Oxidation-reduction equilibrium in glass

Journal of Non-Crystalline Solids, 1982
Oxidation is the loss of an electron and reduction is the reverse: \(F{e^{3 + }} + electronF{e^{2 + }} \) Oxidation and reduction are complementary; without one the other cannot take place. The simultaneous occurrence of reduction and oxidation is commonly known as a 'redox process'.

Interpretation of oxidation-reduction

Journal of Chemical Education, 1970
Presents an interpretation of the oxidation number system based upon the electronegativity principle, thus removing the adjective "arbitrary" frequently found in the descriptions of oxidation number.

Photocorrosion of Cuprous Oxide in Hydrogen Production: Rationalising Self-Oxidation or Self-Reduction.

Angewandte Chemie, 2018
Cuprous Oxide (Cu2 O) is a photocatalyst with severe photocorrosion issues. Theoretically, it can undergo both self-oxidation (to form copper oxide (CuO)) and self-reduction (to form metallic copper (Cu)) upon illumination with the aid of photoexcited ...

Oxidation-Reduction Potentials

1956
The conception of oxidation-reduction potentials as a measure of differences of free energy in hydrogen transport systems is derivable only from equilibrium states. The equations used to describe the effects of varying concentration ratios are based upon the law of mass action and refer only to ideal solutions.
