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 …

Mn 氧化物的 Mn2p 峰具有多个多重分裂峰，类似于 铬 氧化物中的 Cr2p 区。 与 MnO 或 Mn 2 O 3 相比，MnO 2 的 Mn2p 3/2 峰要窄得多。 在 Mn2p 3/2 峰顶部也具有可识别的形状。 可以使用 Mn3s 峰来区分 Mn 的各种氧化态。 此峰具有两个分裂峰。 由非电离的 3s 电子与 3d 价带电子耦合引起。 可通过峰分裂的幅度判断氧化态。 MnO (Mn 2+)、Mn 2 O 3 (Mn3+)、MnO 2 (Mn4+) 的 ΔE 分别为 6.0eV、≥ 5.3eV 和 4.7eV。 [1] MC Biesinger et al., Applied Surface Science 257 …

Mar 15, 2016 · The parameters used to fit XPS spectra for a variety of birnessite samples (Table 1) were vetted over a broad range of multivalent Mn (hydr)oxides and appear to yield accurate results for average Mn oxidation states and concentrations of Mn(II), Mn(III), and Mn(IV).

Jul 12, 2010 · X-ray photoelectron spectroscopy (XPS) is a powerful tool to investigate the mechanisms affecting the fate and transport of Mn in natural and engineered environments.

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 …

X-ray photoelectron spectroscopy (XPS or ESCA) curve fitting procedures, reference materials and useful notes are listed here to provide a starting point for the consistent interpretation of XPS spectra.

Current study depicts an exclusive technique to detect fluoride ions in water using a cost-effective self-powered sensing device using nanostructured Mn doped BaTiO3 as detecting element.

XPS Signals for Manganese, (Mn o) Metal. Spin-Orbit Term, BE (eV) Value, and Scofield σ for Aluminum K α X-rays (1486 eV, 8.33 Ang)

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.

Aug 1, 2010 · This study shows that the use of both the Mn 3s multiplet splitting and the position and shape of the Mn 3p photo-line provides a feasible means of determining the oxidation state of manganese in complex heterogeneous, environmentally important samples.
