Abstract

In this work, the possible synergy effects between Bi₂O₃, MoO₃ and V₂O₅, and between Bi₂Mo₃O₁₂ and BiVO₄, were investigated. The catalytic activity of the ‘‘mechanical mixture’’ of these compounds was measured. The mixture
containing 36.96 mol% Bi₂O₃, 39.13 mol% MoO₃ and 23.91 mol% V₂O₅ (21.43 mol% Bi₂Mo₃O₁₂ and 78.57 mol% BiVO₄), corresponding to the compound Bi_1-x/3V_1-xMo_xO₄ with x = 0.45 (Bi_0.85V_0.55Mo_0.45O4), exhibited the highest
activity for the selective oxidation of propylene to acrolein. The mixed sample prepared chemically by a sol–gel method possessed higher activity than that of mechanical mixtures.
