Mechanochemical Modification of V-Mo-Zr Oxide Compositions

The in uence of mechanochemical treatment by high-energy ball milling in two media (water and ethanol) of di erent V2O5/MoO3/ZrO2 compositions on its structure modi cation and photocatalytic properties is considered. Milling process in both media leads to nal products Zr(V2O7) and Mo4V6O25. Their subsequent thermal treatment provides to formation of Zr(MoO4)2 and V2MoO8 composition. They show the photocatalytic activity in the dyes degradation process in aqueous solution.
