Abstract

In this work, the synergy effect between different phases of bismuth molybdate catalysts was investigated systematically. The catalysts were prepared by spray drying and had a Bi/Mo atomic between 0.57 and 2. It is found that the synergy effect is only observed in mixtures containing γ-phase. A mixture with Bi/Mo ratio = 1.3 consisting of γ- and α-phase, exhibits the highest activity. Less homogeneous ‘artificial mixtures’ exhibit reduced synergy effects when compared to homogeneous ‘in situ mixtures’.
