MoVTeNb mixed oxide catalysts were successfully prepared by reflux with different drying methods. X-ray diffraction (XRD) confirmed the presence of orthorhombic (M1), hexagonal (M2) and (Mo0.93V0.07) 5 O14 phases after spray drying the slurry, while the catalysts obtained from the precipitate and mother liquid contained only hexagonal M2 and (Mo0.93V0.07) 5 O14 phases. Temperatureprogrammed reaction (TPRn) analysis and catalytic test identified the highest activity in the sample synthesized by spray drying in the partial oxidation of propane to acrylic acid.
