✦ Synopsis

Catalysts based on a physical mixture of Ga 2 O 3 and MoO 3 have been prepared and evaluated for propane partial oxidation to propene. The Ga 2 O 3 /MoO 3 catalysts produced appreciable propene yields and it has been demonstrated that the catalyst synergistically combined the alkane activation properties of Ga 2 O 3 with the selective oxidation function of MoO 3 . Studies have probed the influence of varying the Ga/Mo ratio. Catalysts with a 1/1 and 1/3 ratio showed similar catalytic activity, whilst reducing the ratio to 1/10 significantly reduced the propene yield. Comparison of the 1/1 Ga 2 O 3 /MoO 3 catalyst with a 6 wt.% V 2 O 5 /TiO 2 catalyst, which is known to be active for selective propane oxidation, showed that the propene yields were greater for Ga 2 O 3 /MoO 3 .
