It is shown that the valence bond description of the triplet ground state of the oxygen molecule is no less "natural" than that provided by self-consistent field-molecular orbital theory; it is more accurate (unless the self-consistent field result is improved by including configuration ...
Formula and structure:The oxygen chemical formula is O2. The molar mass is 32.00 g/mol. The molecule is diatomic, meaning that is formed by two oxygen atoms that are bound through a double bond. This bond is covalent. Its chemical structure can be written as below, in the common represent...
Commonly, the oxygen molecule is first adsorbed on the catalyst surface to form adsorbed OOH (∗OOH), which becomes HOOH or undergoes O–O bond cleavage to form ∗O [8,14]. SACs and DACs have been developed to exhibit similar or even better ORR performance than Pt and Pt-based elect...

Singlet oxygen generation quantum yield (Φ), which is the probability of a singlet oxygen molecule being generated upon light absorption by the photosensitizer. Calculation Steps: Rate of 1O₂ generation:\(\frac{I \times \lambda \times \Phi \times \left[ S \right]}{{hc}}\), where h...
The presence of nitrogen groups in PDA increases the electrical conductivity and, at the same time, enhances the electron affinity of the catalytic sites to facilitate adsorption of an oxygen molecule, which weakens the strong oxygen–oxygen double bond21. As a result, lower overpotential in ORR ...
In the overall reaction cycle, the intermediate formed by reaction of catalase haem iron with H2O2, termed ‘compound I’, can be reduced by a second molecule of H2O2 (catalatic reaction) or by an alternative hydrogen donor (peroxidatic reaction).Thioredoxin system...

whose formula is O2. This form of oxygen is also known as molecular oxygen and can be found in the atmosphere or dissolved in oceans. Two atoms of oxygen are chemically bonded to form the dioxygen molecule. The bond between these two atoms is double covalent since two pairs of electrons ar...
