Palladium Oxide (PdO) by XPS

X-ray photoelectron spectroscopy (XPS) spectra of palladium oxide (PdO) are presented. Clean, ground PdO powder was pressed into In foil and analyzed with a Surface Science Instruments SSX-101 M-Probe ESCA instrument using monochromatized Al Kα x rays. Spectra include a survey scan, the Pd 3d, 3p, 3s, 4s, 4p regions, the O 1s, and valence band regions, and the O KLL, Pd MNN and MNV Auger transitions.
