Aug 1, 2018 · X-ray photoelectron spectroscopy (XPS) proved to be an effective tool for determination of the cerium ionic composition (Ce3+ and Ce 4+).

Dec 1, 2023 · Analysis of cerium environments within materials by XPS is a challenging affair, with detailed understanding of the spectral envelopes requiring extensive peak modelling.

Data Collection Settings for Cerium (Ce) Conductivity: Cerium readily develops a native oxide that is sensitive to Flood Gun – Differential Charging Possible – float sample recommended; Primary Peak (XPS Signal) used to measure Chemical State Spectra: Ce (3d 5/2) at 883.8 eV

Cerium is a very useful material in heterogeneous catalysis and other fields due to it’s ability to store and move oxygen, but the XPS spectrum is not straightforward to deconvolute due to complications arising from final-state effects. Typically, cerium is observed as either Ce(III) or Ce(IV) and both states produce complex spectra.
