摘要：

SBA-15 supported Mo catalysts (Mo-y/SBA-15) were prepared by an ultrasonic assisted incipient-wetness impregnation method. The physical and chemical properties of the catalysts were characterized by means of N-2-adsorption-desorption, XRD, TEM, UV-Vis, Raman, XANES and H-2-TPR. The results showed that a trace amount of MoO3 was produced on high Mo content samples. Turn-over frequency (TOF) and product selectivity are dependent on the molybdenum content. Both Mo-0.75/SBA-15 and Mo-1.75/SBA-15 catalysts give the higher catalytic activity and the selectivity to the total aldehydes for the selective oxidation of C2H6. At the reaction temperature of 625 degrees C, the maximum yield of aldehydes reached 4.2% over Mo-0.75/SBA-15 catalyst. The improvement of the activity and selectivity was related with the state of MoOx species.
