Abstract

There has been a longstanding debate and controversy in the literature with regard to the determination by XPS of the exact oxidation state of a molybdenum species commonly observed in the passive films of stainless steel. In this paper we have compared both the XPS and ESR analyses of molybdenum oxybydroxides previously postulated to contain Mo(V) as well as Mo(IV) and Mo(VI). The compositions of these compounds closely resemble those found in the passive films of Mo-bearing stainless steel. It has been shown that the same Mo species exhibiting an XPS Mo 3d_5/2 spectrum binding energy value of 230.8 eV is observed to exhibit an ESR spectra having a g factor of 1.921, which corresponds to Mo(V).
