摘要：

Oxidative dehydrogenation of propane was studied over MgMoO4-MoO3 catalysts with a wt% of MoO3 varying from 0 to 100. The samples were characterized by XRD, EPR, DTA, laser Raman, and BET. The catalytic behavior of the mechanical mixtures was quite different from that of pure phases. These differences were discussed in terms of possible synergy effects between the phases. Propane conversion and selectivity to propene were closely related to the change in redox properties of the catalysts due to the appearance of Mo5+ ions.
