Molecular oxygen oxidation

Their rates are decreased or the reactions are suppressed entirely by substances that scavenge free radicals (e.g., nitric oxide, molecular oxygen, or benzo-... 

Depending on the water composition other radical species are formed, such as carbonate and chloride radicals. This imposes net oxidizing conditions at the water—fuel interface because the generated oxidants, molecular oxygen and hydrogen peroxide, predominate under a radiation, and other radical species like OH- or CQf- are more active than the generated reductants, mainly molecular hydrogen. This is why we propose that the spent fuel-water interface is a dynamic redox system, independently of the conditions imposed on the near field (Merino et al. 2001). 

It was clear that if the formulation O2+ [PtF,]- were true, then platinum hexafluoride should oxidize molecular oxygen. A sample of platinum hexafluoride was therefore prepared, and since it has a vapor pressure of 80 mm. at room temperature, the interaction with molecular oxygen was followed tensimetrically. The deep red (bromine colored) platinum hexafluoride vapor reacted instantly with the oxygen in a 1 1 molar ratio to give the familiar red compound. Interestingly, the solid made by this method at low temperatures, is iso-morphous and almost isodimensional with rhombohedral potassium hexafluoroplatinate (V). At higher temperatures transition to the cubic phase occurs. 

If a peroxide is reduced, the product of reduction must contain oxygen in the -2 oxidation state, as in H2O or OH . If a peroxide is oxidized, molecular oxygen is formed. (A superoxide is possible.)... 

The most inexpensive and innocuous oxidant, molecular oxygen, cannot be used efficiently.
