MOF-derived electrocatalysts for oxygen reduction, oxygen evolution and hydrogen evolution reactions
Chemical Society Reviews, 2020The morphology and composition design of MOF-derived carbon-based materials and their applications for electrocatalytic ORR, OER and HER are reviewed.

Oxygen evolution from BF3/MnO4−
Chemical Communications, 2011MnO(4)(-) is activated by BF(3) to undergo intramolecular coupling of two oxo ligands to generate O(2). DFT calculations suggest that there should be a spin intercrossing between the singlet and triplet potential energy surfaces on going from the active intermediate [MnO(2)(OBF(3))(2)](-) to the O···O coupling transition state.

Oxygen evolution reaction is evinced as one of the main rate-determining steps for clean energy production, energy security supply and therefore for the evolution of a sustainable society. The production of clean energy, the security of energy supply (autonomy) and lower cost of energy supply constitute the main key points for a sustainable future.

Understanding of Oxygen Redox in the Oxygen Evolution Reaction
Advanced Materials, 2022AbstractThe electron‐transfer process during the oxygen evolution reaction (OER) often either proceeds solely via a metal redox chemistry (adsorbate evolution mechanism (AEM), with metal bands around the Fermi level) or an oxygen redox chemistry (lattice oxygen oxidation mechanism (LOM), with oxygen bands around the Fermi level).

Evolution of Oxygenic Photosynthesis
Annual Review of Earth and Planetary Sciences, 2016The origin of oxygenic photosynthesis was the most important metabolic innovation in Earth history. It allowed life to generate energy and reducing power directly from sunlight and water, freeing it from the limited resources of geochemically derived reductants. This greatly increased global primary productivity and restructured ecosystems. The release

Electrocatalysis of oxygen evolution
International Journal of Hydrogen Energy, 1982Abstract The electrocatalytical properties of various mixed oxides between Ni and/or Co and La in the oxygen evolution reaction have been examined. The highest electrocatalytical activity has been obtained for a non-stoichiometric oxide between Ni and Co of nominal formula Ni0.2Co0.8LaO3.

Oxygen toxicity and microbial evolution
Biosystems, 1991It is postulated that the role of oxygen toxicity in the evolution of life strongly depends on the origin of molecular oxygen, due to the strong redox buffering capacity of Precambrian waters containing large amounts of ferrous and manganese cations. The critical selective pressure could be observed only after aerobic photosynthesis had been developed,

Oxygen Evolution and Manganese
1977The overall equation of photosynthesis does not permit a distinction between H2O or CO2 as the source of molecular oxygen. Both of these have been alternatively proposed as the oxygen source.

Timescales of Oxygenation Following the Evolution of Oxygenic Photosynthesis
Origins of Life and Evolution of Biospheres, 2015Among the most important bioenergetic innovations in the history of life was the invention of oxygenic photosynthesis-autotrophic growth by splitting water with sunlight-by Cyanobacteria. It is widely accepted that the invention of oxygenic photosynthesis ultimately resulted in the rise of oxygen by ca. 2.35 Gya, but it is debated whether this occurred

Calcium Activated Oxygen Evolution
1990In PSII preparations lacking the 17 and 23 kDa water-soluble polypeptides, Cl− and Ca+2 are required for oxygen evolution (1). The role each of these ions play in oxygen evolution is not understood. There is disagreement in the literature about the dissociation constants (2–5) for each of these ions.
