XPS 谱图解读. K2p 峰具有明显的自旋轨道分裂峰(Δ 氯化物 =2.8eV)。 较弱的 K2p 峰很容易与芳香族化合物中的 C1s (CF 2) 峰或 C1s 卫星结构混淆。 通过识别预期的 K2p 自旋-轨道分量,可以确定 K2p 与 C1s 峰。还检查 K2s 峰,结合能 ~378eV。 一般性注释
High resolution X-ray Photoelectron Spectroscopy (XPS) study of K
2012年1月15日 · In this work we report a core level XPS study of K 2 O–SiO 2 glasses, emphasizing the O 1s, Si 2p and K 2p spectral lines. The XPS data provide evidence for two types of BO atoms and the presence of O 2−; an oxygen atom not bonded to a silicon atom.
this work aims at providing XPS characterization of numerous commercial K-based reference compounds, including some that were still missing in the literature. In particular, absolute and relative binding energy values are given and compared to correspond-
对 K 基参考化合物进行 XPS 分析,以便对 K 离子电池中的固体电 …
然而,迄今为止,KIB 中固体电解质中间相 (SEI) 的 X 射线光电子能谱 (XPS) 分析仍然基于锂离子和钠离子文献。 考虑到碱金属之间的第一电离电位差预计会显着改变 XPS 观察到的给定 M 基(M = Li、Na 或 K)化合物的结合能值,这可能会导致对结果的错误解释。 因此,这项工作旨在提供许多基于 K 的商业参考化合物的 XPS 表征,包括一些文献中仍然缺失的化合物。 特别是,给出了绝对和相对结合能值,并与相应的 Li 和 Na 对应物进行了比较。

2021年9月29日 · As for Li- and Na-ion batteries, the electrolyte reactivity (i.e., the salt and solvent decomposition) also plays a crucial role in the electrochemical performance of K-ion batteries (KIBs). However, X-ray photoelectron spectroscopy (XPS) analysis of a solid electrolyte interphase (SEI) in KIBs remains based on Li-ion and Na-ion literature so far.

XPS: It arises as a consequence of the build-up of a positive charge at the surface of non-conducting specimens. The rate of photo-electron loss is greater than that of their replacement from within the specimen. It produces a retarding field at the surface that will shift the peaks (reduce the KE of the ejected electrons). Suggestions:
