| Abstract: | The oxidation of a heteropoly blue (HPB) of the composition NaxH9-xPMo9V3O40 with molecular oxygen has been studied by the method of catalytic vanadyl oxidation. It is shown that the reduction of an oxygen molecule requires the addition of a fourth atom of V(IV) in the form of a vanadyl ion to the heteropoly anion.
