Interpretation of XPS spectra. Mn2p peak has significantly split spin-orbit components (Δ metal =11.2eV). Mn2p peaks have asymmetric shape for metal. Mn oxide peaks are significantly shifted to higher binding energy than the metal. A well resolved …

X射线光电子能谱 （XPS） 是一种研究 物质表层元素组成与离子状态 的表面分析技术。 它的基本原理是用 单色射线 照射样品，使样品中原子或分子的电子受激发射，然后测量这些电子的能量分布。 通过与已知元素的原子或离子的不同壳层的电子的能量相比较，就可确定 未知样品表层中原子或离子的组成和状态。 由于XPS在分析 元素组成与化学环境 方面具有独特的优势，因此它在各个学科中都得到了广泛的应用。 无论何种档次的SCI论文，我们也总能见到它的身影。 然而 …

2016年3月15日 · In this contribution an empirical methodology using X-ray photoelectron spectroscopy (XPS) is developed to quantify the oxidation state of hydrous multivalent manganese oxides with an emphasis on birnessite, a layered structure that occurs commonly in soils but is also the oxidized endmember in biomimetic water-oxidation catalysts.

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.

In case of the high-resolution XPS spectrum of Mn 2p (Fig. 1d), two major peaks are found at 641.3 and 653.3 eV for the Mn 2p 3/2 and Mn 2p 1/2 states, respectively [36].

The Basic XPS Information Section provides fundamental XPS spectra, BE values, FWHM values, BE tables, overlays of key spectra, histograms and a table of XPS parameters.

Interpretation of XPS spectra. Mn2p peak has significantly split spin-orbit components (Δ metal =11.2eV). Mn2p peaks have asymmetric shape for metal. Mn oxide peaks are significantly shifted to higher binding energy than the metal. A well resolved …

2010年7月12日 · X - ray photoelectron spectroscopy (XPS) was used to identify Mn (II), Mn (III), and Mn (IV) in the surfaces of pure oxide standards and filtration media samples from drinking water treatment plants through the determination of the magnitude of the Mn 3s multiplet splitting and the position and shape of the Mn 3p photo - line.

Calculated Mn (2p 3/2 ) X-ray photoelectron spectra (XPS) of Mn 2+ , Mn 3+ , and Mn 4+ free ions are strikingly similar to Mn (2p 3/2 ) spectra of Mn 2+ -, Mn 3+ -, and Mn 4+ -oxides and oxyhydroxides, indicating that these ions adopt high spin …
