2. Oxygen evolution - Wikipedia

   en.wikipedia.org/wiki/Oxygen_evolution

   Oxygen evolution is the process of generating molecular oxygen (O 2) by a chemical reaction, usually from water. Oxygen evolution from water is effected by oxygenic photosynthesis, electrolysis of water, and thermal decomposition of various oxides.

3. Catalytic oxidation - Wikipedia

   en.wikipedia.org/wiki/Catalytic_oxidation

   Catalytic oxidation. Catalytic oxidation are processes that rely on catalysts to introduce oxygen into organic and inorganic compounds. Many applications, including the focus of this article, involve oxidation by oxygen. Such processes are conducted on a large scale for the remediation of pollutants, production of valuable chemicals, and the ...

4. Heterogeneous water oxidation - Wikipedia

   Generally these spinels are ofter coated over the carbon materials and reduced further to create oxygen vacancy in their lattice to enhance the water oxidation capabilities.

5. Oxygen - Wikipedia

   en.wikipedia.org/wiki/Oxygen

   Oxygen is a chemical element; it has symbol O and atomic number 8. It is a member of the chalcogen group in the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds. Oxygen is the most abundant element in Earth's crust, and after hydrogen and helium, it ...

6. Geological history of oxygen - Wikipedia

   en.wikipedia.org/wiki/Geological_history_of_oxygen

   Oxygen began building up in the atmosphere at approximately 1.85 Ga. At current rates of primary production, today's concentration of oxygen could be produced by photosynthetic organisms in 2,000 years. [4] In the absence of plants, the rate of oxygen production by photosynthesis was slower in the Precambrian, and the concentrations of O 2 ...

7. Electrocatalyst - Wikipedia

   en.wikipedia.org/wiki/Electrocatalyst

   An electrocatalyst is a catalyst that affects the activation energy of an electrochemical reaction. [8] Shown below is the activation energy of chemical reactions as it relates to the energies of products and reactants. The activation energy in electrochemical processes is related to the potential, i.e. voltage, at which a reaction occurs.
