A comparison study on the structure and performance of Mo-V-O and Mo-V-Te-O catalysts synthesized hydrothermally with ultrasonic pretreatment for propane oxidation
The Mo1.00V0.80O (n) and Mo1.00V alpha Te0.17O (n) (alpha = 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, H-2-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.
