Oxidation of vanadium in atomic and molecular oxygen at low pressures

DFT study of the V(IV)/V(V) oxidation mechanism in the presence of N-hydroxyacetamide

“…The dissolved oxygen is reduced leading to the oxidation of the V(IV) through several different intermediates, including hydroxyl radicals and hydrogen peroxide. In several studies, the ability of vanadium coordination compounds to catalyze the conversion of molecular oxygen to hydroperoxides at low pressures [33] and the conversion of hydroperoxides to hydroxyl radical have also been shown. The formation of hydrogen peroxide and radicals in oxi-reduction reactions involving molecular oxygen is well known and discussed in the literature [1,34,35].…”
