Figure 1: Mo metal XPS spectra(1)
As can be seen in figure 1, the peaks of Mo metal are asymmetric in shape, however the oxides will possess a symmetric shape.
Typical binding energies for common Mo species may be found in table 1.
|Species||Binding energy / eV||Charge Ref||Ref|
|Mo||227.8||Au 4f / 84 eV||2|
|MoO2||228.7||Au 4f / 84 eV||2|
|MoO3||232.8||Au 4f / 84 eV||2|
