Peculiarities of the effect of the products of an aqueous mechanoactivated filtrate on the state and properties of dispersed vanadium pentaoxide

Influence of mechanoactivated water filtrate products on the catalytic properties of a dispersed substance is investigated and first observed. In a mechanoactivated water suspension, powdery V2O5 reduces to VO2, whose surface contains polyvanadate structures that are precipitated from high concentrated lucid orange solutions. Unusually high catalytic activity of a mechanosynthesized vanadium dioxide powder in the selective oxidation reactions of benzene, n-butane, and propane is connected with that the structures of active sites into polyvanadates and vanadyl pyrophosphate as the most active catalyst of the given reactions coincide practically
