Abstract
The influence of molybdenum oxide on the dispersion and activity of vanadium oxide supported on alumina was investigated. A series of MoO3 catalysts were prepared using monolayer V2O5/γ-Al2O3 catalysts by impregnation method. The catalysts were characterized by X-ray diffraction and oxygen chemisorption at −78 °C. The catalytic properties were evaluated for the vapour-phase oxidation of methanol. The addition of MoO3 to V2O5/γ-Al2O3 results in the decrease of dispersion of vanadia and also the activity for the oxidation reaction. However, the selectivity of formaldehyde was found to increase with MoO3 loading indicating that MoO3 created additional sites for partial oxidation reaction.
