Oxidation on metal oxides

Mn(II) oxidation on metal oxides. The rate of oxidation of Mn(II) in the presence of y-FeOOH can be described by the following equation (26) ... 

In the studies described above the experimental conditions were chosen for experimental convenience, so they may differ greatly from those found in natural waters. To try to identify the factors that might influence Mn(II) oxidation on metal oxides surfaces in natural waters, the surface equilibria and kinetic models developed above can been used to predict the time scales for Mn(II) oxidation in these waters. 

Further evidence for photoassisted interconversions between nitrous oxides, nitric oxide and other nitrogen oxides on metal oxide surfaces emerged from studies with the dynamic mass spectrometer system of flash-initiated changes at N O/ZnO interfaces. Fig. 13(a) illustrates mass spectra of the gas mixture adjacent to an 14N1SN160/Zn0 interface prior to a flash and then 100 ms after a flash, and the broken line demonstrated that a quite different mass spectrum was detected by the DMS system 100 ms after flash illumination. The large enhancement of m/e = 30 (14N160+), smaller enhancement of m/e = 31 (1SN160+), and absence of...

The likely role of amide species produced by oxidation of Lewis-site coordinated ammonia finds support from the studies concerning ammonia activation and oxidation on metal oxide catalysts.
