2008年2月15日 · Samples of the iron oxides Fe 0.94 O, Fe 3 O 4, Fe 2 O 3, and Fe 2 SiO 4 were prepared by high temperature equilibration in controlled gas atmospheres. The samples were fractured in vacuum and high resolution XPS spectra of the fractured surfaces were measured.

The XPS Spectra section provides raw and processed survey spectra, chemical state spectra, BE values, FWHM values, and overlays of key spectra. Atom% values from surveys are based on sample, as received, and Scofield cross-sections. Atom% values are corrected for IMFP and PE. Peak-fits are guides for practical, real-world applications.

2014年6月1日 · In this study, the surface composition of oleylamine/oleic acid-coated Fe 3 O 4 nanoparticles was investigated by X-ray photoelectron spectroscopy (XPS) to characterize the nature of the surfactant chemisorbed to the surface and to determine the effects of the capping agent on the composition of Fe3 O 4 substrate.

1996年10月1日 · 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.

Modified/updated fitting parameters for FeO, FeOOH and Fe3O4 are now included in Table 1 from work presented in reference [6]. In particular the analysis and fitting of FeO is improved substantially as the new FeO standard, sputter cleaned with a GCIS (not available during the original work in [3,5]), is free of low levels of surface Fe2O3 ...

结果表明高分辨率 XPS 技术可用于确定金属氧化物中的 Fe2+/Fe3+ 比率。 该技术具有应用于其他过渡金属氧化物系统的潜力。 铁氧化物 Fe0.94O、Fe3O4、Fe2O3 和 Fe2SiO4 的样品在受控气体气氛中通过高温平衡制备。 样品在真空中断裂并测量断裂表面的高分辨率 XPS 光谱。 Fe2+ 和Fe3+ 的Fe 3p 峰位置和峰形参数分别来自2FeO·SiO2 和Fe2O3 标准样品的Fe 3p XPS 光谱。 使用这些参数，分析了 Fe3O4 和 Fe1-yO 的 Fe 3p 峰。 结果表明高分辨率 XPS 技术可用于确 …

2021年3月3日 · The Al K alpha, 1486.6 eV, based x-ray photoelectron spectroscopy (XPS) of Fe 2p and Fe 3p for Fe(III) in Fe 2 O 3 and Fe(II) in FeO is compared with theoretical predictions based on ab initio wavefunctions that accurately treat the final, core-hole, multiplets. The principal objectives of this comparison are to understand the multiplet ...
