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 Bi1-x/3V1-xMoxO4 with x = 0.45 (Bi0.85V0.55Mo0.45O4), 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.
