2011年1月15日 · Practical approach to deconvolution of complex X-ray photoelectron 2 p spectra of Cr, Mn, Fe, Co and Ni species. Full disclosure of peak-fitting parameters presented as these are needed to reproduce fitting procedures. Comparison to quality standard samples provides best opportunity to understand species present. This approach takes into...

2024年9月18日 · Both the in-depth chemical composition and the topological structure of thin films can be investigated by X-ray photoemission (XPS) coupled with sequential low-energy ion sputtering (depth profiling), thanks to the modeling of the XPS spectra at each step of the depth profile measurement.

2020年8月1日 · Three novel ozonation catalysts, i.e. cobalt-based, nickel-based and cobalt/nickel-based metal-organic frameworks (Co-MOF, Ni-MOF and Co/Ni-MOF), were synthesized, characterized by XRD, SEM, N2 sorption-desorption isotherms, FTIR and XPS, and applied in catalytic ozonation for atrazine removal.

The objective of this study is to develop a method for decomposing XPS spectra of 2p core levels for nickel and cobalt-oxidized compounds. This methodology was then employed to study the passivation layer of the Co20Ni80 alloy.

XPS 光谱解读. Ni2p 峰具有明显的自旋轨道分裂峰 (Δ 金属 =17.3 eV)。 镍金属谱图的峰形复杂。 主峰与卫星特征峰混杂。 Ni金属的卫星峰不要和氧化镍的峰混淆了。 镍化合物也可能具有复杂、多重劈裂的峰形。

XPS 谱图解读. Co2p 峰具有明显的自旋轨道分裂峰（Δ 金属 =14.99eV） Co2p 区与自身一些较弱的 Co LMM 俄歇峰重叠，必须注意不要将该峰误判为 XPS 峰。 金属的 Co2p 峰形不对称。 高分辨金属Co的2p谱图显示了复杂的结构。 可以使用 Co2p 谱的卫星峰区分 Co 的各种氧化态。

2006年5月1日 · A current interpretation of XPS spectra of Ni metal assumes that the main 6 eV satellite is due to a two hole c3d 9 4s 2 (c is a core hole) final state effect. We report REELS observation in AES at low voltages of losses (plasmons and inter-band transitions) corresponding to the satellite structures in Ni metal 2p spectra.

2024年9月18日 · The XPS analysis, coupled with sequential ion sputtering, revealed that the passive layer of the Co 20 Ni 80 alloy is heterogeneously covered with either oxidized cobalt compounds or oxidized nickel compounds. The method used also demonstrates that the chemical heterogeneity is associated with the thickness heterogeneity of the passive layer.

2023年2月16日 · Surface analysis by X-ray photoelectron spectroscopy and time-of-flight secondary ion mass spectrometry was applied to investigate the origin of the enhanced surface passivity and resistance to a...
