From: Interfacial charge distributions in carbon-supported palladium catalysts
Lab-source XPS spectra for Pd/PS200 to Pd/PS800 catalysts. The deconvolved peaks were assigned to Pd metal at 335.1 eV (blue), Pdδ+ at 335.95 eV (orange), and Pd oxides at 336.9 eV and 337.85 eV (green). The increasing contribution of Pdδ+ with treatment temperature largely contributes to the shoulder that appears in the overall spectra between 336 and 337 eV
