文献中Co的XPS分析，哪个才是正确的？_仪器信息网社区
2021年9月16日 · 文献中Co的XPS分析，哪个才是正确的？,文献中的这几个钴的2p3/2峰都不是完全对称的，看起来是需要分峰才能拟合得更好，然后就发现了以下几种分峰方式（1）分成二价钴和三价钴，三价钴在低能方向。二价钴的结合能更高（2）只有一个三价钴的峰，但是,
Multiplet splitting in the 3p XPS of low-spin Co(III) compounds
1983年1月1日 · We have measured the 3p XPS spectra of Co(NH 3) 2 Cl 3, Co(acetylacetonate) 3 and K 3 Co(CN) 6, all low-spin octahedral compounds, and compared the spectra with the predicted multiples structure. The agreement is good.

XPS study of cobalt-ceria catalysts for ammonia synthesis – The ...
2018年9月1日 · X-ray photoelectron spectroscopy (XPS) was subsequently used to investigate the evolution of surface composition. High resolution X-ray photoelectron analysis confirms total reduction of cobalt oxide into Co metallic form. After exposure to hydrogen, Ce 4+ ions prevail in the structure of cerium oxides identified on the surface.
