Abstract

The Mo_1.00V_0.80O _n and Mo _1.00V_αTe_0.17O _n (α = 0.40-1.00) catalysts were prepared hydrothermally with ultrasonic pretreatment for propane partial oxidation. The fabricated catalysts were characterized by BET, XRD, Raman, XPS, EPR, SEM, H₂-TPR, and NH₃- calorimetric techniques. It is revealed that the content of vanadium in the catalysts is crucial for the generation of phase structure essential for good performance. The role of Te in the catalytic system and the effect of ultrasonic treatment during catalyst fabrication on catalyst properties are interpreted based on the characterization and reaction results obtained.
