Abstract

A series of Mo-Co catalysts supported by A1₂O₃-USY with different Mo/(Mo + Co) atomic ratio were prepared and used for gas phase selective oxidation of toluene to benzaldehyde. The structure and surface properties of the catalysts were characterized by X-ray diffractometry (XRD) and X-ray photoelectron spectroscopy (XPS). The best catalytic activity result with a 11.37% benzaldehyde yield could be reached when the catalyst has a ratio of n_Mo : (n_Mo + n_Co) = 0.34, and temperature at 480°C with 6000.0 h^-1 of space velocity, and 100 of the air/toluene molar ratio.
