摘要:
We report x-ray photoemission spectra of the surface of iron oxide (FeO) particles. The research grade high purity FeO sample was commercially obtained from Alfa/AESAR. The XPS spectra were measured with the Physical Electroncs Model 5400 x-ray photoelectron spectrometer using unmonochromatized MgKαx-rays at two pass energy settings corresponding to analyzer resolutions of 1.34 and 0.54 eV. We present the survey spectrum (binding energy range of 0–1100 eV) measured at an analyzer energy resolution of 1.34 eV. Multiplexes of the C 1s, O 1sand 2s, and Fe 2pand 3pphotoemission lines, valence band region as well as the FeLVVAuger line were measured at an analyzer energy resolution of 0.54 eV. The XPS data indicate that the surface of FeO powdered material consists mainly of Fe2O3with small quantities of FeOOH, oxidized carbon, and hydrocarbon as contaminants.
