Law, Theoretical and experimental study of the electronic structures of MoO3 and MoO2, J. Free, fully featured, XPS data analysis software for Windows 95/98. Fairley, Generalized molybdenum oxide surface chemical state XPS determination via informed amorphous sample model, Appl. Perhaps some theoretical peak modelling may be useful here. Some very speculative comments on these results - read at your own risk.įor point 3 - Are we losing the screened (conductive) portion of the Mo(IV) in unconductive mixed oxide samples?įor point 4 - Is the peak shape obtained for Mo(V) using a multivariate approach showing us a multiplet split peak shape (with or without shakeups etc.) or is it showing us the Mo(VI) component that always must be present when Mo(V) is present? This necessary Mo(VI) component will vary with the peak area of the Mo(V) component (and thus will be elucidated as part of the Mo(V) peakshape). Peak shapes for Mo(V) from this work also suggest a two (or more) component Mo 3d5/2 structure. An explanation of why this is so is still to be found.Ĥ) Mo2O5 can only be present when Mo(VI) species are also present. This is something we've also seen in our studies here. The Mo(IV) peak also moves to a higher binding energy. Mo 3d3/2 unscreened: 234.21 eV (a+4.94), FWHM 2.21 eV, weight 0.83ģ) This complex structure for MoO2 seems to be lost for mixed oxide samples (see Figure 9). The sharper, slightly asymmetric main peak at 229.3 eV and broader higher binding energy peak at 231.0 eV are ascribed to screened and unscreened final states. The Mo 3d peak shape for MoO3 is a simple spin-orbit doublet.Ģ) Pure MoO2 has a complex Mo 3d5/2 peak shape showing a two component (see Figure 4) structure. Some key points from this paper to consider for analysis of molybdenum oxides.ġ) MoO3 degrades over time under X-ray exposure. Two XPS fitting models for a Mo 3d spectrum of an amorphous molybdenum oxide sample: (A) Informed Amorphous Sample Model, and (B) Purely Synthetic Model.* The synthetic LF components were summed to form a single complex line shape for MoO2 (green) once a consistent model with the experimental data emerged.*įigure 9 from. 2021 XPS International, LLC All Rights Reserved.Figure 4B from.
