2022年2月1日 · The Mn3s XPS spectra (Fig. 1 b) demonstrates two split components caused by coupling of non-ionized 3 s electron with 3d valence-band electrons; the magnitude of the peak splitting can be used to differentiate between the Mn oxidation states, where ΔΕ is around 6 eV, 5.3 eV and 4.7 eV for Mn II, Mn III and Mn IV, respectively [60].

Layered double hydroxides (LDHs) have been intensively studied for phosphate (P i) removal but suffer from poor stability and low sorption affinity under ambient conditions. In this paper, well crystallized Mn II Fe II Fe III -Cl, Mn II Fe III -CO 3 and novel Mn IV Fe III …

XPS 谱图解读. Mn2p 具有明显的自旋轨道分裂峰（Δ 金属 =11.2eV）。 金属的 Mn2p 峰形不对称。 相对于金属，Mn 氧化物峰明显移向更高的结合能。 金属的高分辨率 Mn2p 谱显示了多重分裂。 [1]

Manganese ion (Mn²⁺) bonded nitrogen-doped graphene quantum dots (Mn (II)-NGQDs) with water solubility have been successfully synthesized by a simple, one-pot hydrothermal carbonization, using...

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.

Download scientific diagram | XPS spectra of Fe (III)-Alg (A,B) and Mn (II)-Alg (C,D). from publication: Iron and Manganese Alginate for Rechargeable Battery Electrodes | We present a...

Figure 2 a−c shows the Mn 2p fine spectra of MnO x films (a) after an in-line transfer, (b) after air exposure, and (c) after electrochemistry. Each spectrum consists of Mn 2p 3/2 and 2p 1/2 peaks...

xps谱图分析——主线. 最强的光电子线常常是谱图中强度最大、峰宽最小、对称性最好的谱峰，称为xps谱图中的主线。每一种元素(h和he除外)都有自己最强的、具有表征作用的光电子线，它是元素定性分析的主要依据。

最近在分析xps的谱图，有一些问题，望高人指点： 1、关于结合能，感觉与标准谱图有偏差，是根据C1s峰进行校正还是主峰进行校正？ 2、下图中将第二个峰定义为卫星峰（859eV)，看到文献中有提到零价镍的峰面积占总面积的80%，卫星峰小于20%。
