The relationship between the Mo oxidation states measured by X-ray photoelectron spectroscopy (XPS) and the NH_x species was discussed based on results of temperature-programmed desorption (TPD). From the XPS analysis, the major Mo oxidation states were found to be Mo^<3+> and Mo<4+> for 1.0-18.7wt% Mo/Al_2O_3 nitrided at 973K.The TPD results indicated that the desorption of nitrogen and hydrogen from the nitrided Mo/Al_2O_3 were deconvoluted to those of NH_x {α_N(NH_X, X=0), β_N and γ_N (NH_X, X=0.6 to 1.5} adsorbed on molybdenum species. The nitrogen species (NH_X, X=0) adsorb only on Mo^<3+> ions of the 973K-nitrided Mo/Al_2O_3, but NH_X species (X=0.6-1.5) adsorb on either Mo^<3+>or Mo^<4+>ions.
