The dynamic structure of Mo-O species in Ag-Mo-P-O catalyst was studied by in situ confocal microprobe laser Raman spectroscopy (LRS) and catalytic test. The results indicate Mo-O species of MoO₃ transformed to Mo-O species of AgMoO₂PO₄ in C₃H₈/O₂/N₂ (3/1/4) flow at 773 K. This behavior is closely relative to oxidative dehydrogenation of propane and intrinsic properties of Mo-O species. The Mo-O species of AgMoO₂PO₄ may be active species for oxidative dehydrogenation of propane.
