Ion implantation has profound effects upon the reaction of iron with oxygen at 400掳C and 0.1 Torr. Self-implantation results in the formation of a fine-grained oxide; the oxidation rate is qreater than that found for pure iron and this is attributed to a greater number of short-circuit ...
Oxygen transfer from percarboxylic acids to (ethylenediaminetetraacetato)iron(III) ((EDTA)FeIII) has been investigated (solvent CH3OH; T 30°C), using 2,4,6-tri-tert-butylphenol (TBPH) as a trapping reagent for the reactive iron-oxo intermediate formed upon oxygen transfer. In the presence...
The reaction between dissolved sulfide and synthetic iron (oxyhydr)oxide minerals was studied in artificial seawater and 0.1 M NaCl at pH 7.5 and 25°C. Electron transfer between surface-complexed sulfide and solid-phase Fe(III) results in the oxidation of dissolved sulfide to elemental sulfur, ...
reproduce all data, suggesting the reaction could be well explained by efficient crossing from the sextet to quartet surface, with a rigid near thermoneutral barrier accounting for both the inefficiency and strong negative temperature dependence of the reactions over the measured range of thermal ...
At 100 ppm, the oxygen binding energy for the reaction ½ O2 + 2e− = >O2− is shifted 0.34 eV relative to its standard value. The formation energy of Fe3O4 is 0.2 eV more exothermic than H2O. Both of these factors enhance the driving force for oxygen ...
