Abstract
Molybdenum oxides microspheres with prominent MoO2 phase were produced successfully by ultrasonic spray pyrolysis under reducing conditions. Ethylene glycol addition in the precursor solution was found to promote complete truncation of regular molybdenum oxides particle geometry into rectified spherical micro particles during spray pyrolysis. It also removed the MoO3 and Mo4O11 phases, while maintaining nanocrystalline MoO2 phase structure. However, addition of EG reduced the surface area and increased the pore size rather significantly, which might adversely affect the catalytic performance of MoO2 microspheres. Catalytic activity of the product molybdenum oxides was investigated for partial oxidation of n-dodecane.
