摘要:
We report x-ray photoemission spectra of the surface of iron (III) oxyhydroxide (α-FeOOH) particles. Research grade purity (99.0%)α-FeOOH sample was commercially obtained from Alfa/AESAR. The XPS spectra were measured with the Physical Electronics Model 5400 X-ray Photoelectron Spectrometer using unmonochromated MgKαx-rays at two pass energy settings corresponding to analyzer energy 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, Fe 2pand 3pphotoemission lines, valence band region as well as the FeL3VVAuger line were measured at an analyzer energy resolution of 0.54 eV. The XPS spectra indicate that the surface ofα-FeOOH powdered material consists mainly of its bulk chemistry with small quantities of oxidized carbon and hydrocarbon as contaminants.
