2023年6月15日 · Cu Auger LMM spectra for the time-controlled oxidation at atmospheric pressure. The observed peaks gradually shift to lower kinetic energies with increasing oxidation time.

2003年10月1日 · Analysis of the spectra of Cu 2p and Cu LMM lines of the melt-quenched Cu 2 O–Na 2 O–SiO 2 glass shows remarkable X-ray irradiation effects. X-ray induces the Cu 2p peak shifts towards the lower binding energy side and finally it …

针对审稿人的问题，就像你们测试中心的老师说的 画一个Cu LMM的图。 然后把Cu0 Cu1+ 和/或Cu2+ 确定出来 做一下分峰 然后把它们的atomic ratio确定一下 再做一个比例比较 结合你的结论进行讨论。 Cu的XPS文献较多 讨论 LMM的也很多 不需要拘泥于你本专业的文献 可以广泛参考。 至于你说的 923.8和917.8相差很大的问题 可能因为矫正的问题和仪器的问题 有一定的差别是正 …

In the spectrum of Cu LMM (Figure 2d), characteristic peaks located at 569.8 eV and 568.1 eV are respectively assigned to Cu (I) (Cu2O) and Cu [15], while the peak at 572.7 eV corresponds to Cu...

There are small binding energy shifts of some compounds compared to copper metal. Chemical state differentiation can be difficult with XPS only. Collect principal Cu LMM peak, as well as Cu2p. There are bigger chemical shifts observed for Cu LMM compared to Cu2p. Use Wagner plot to help assign chemistry.

The Cu LMM peak shape (in addition to the Auger parameter and Cu 2p3/2 peak position and shape) can also be useful in determining Cu chemical states. It is particularly useful when determining Cu metal versus Cu (I) in the absence of Cu (II) species.

2014年12月1日 · We have performed these calculations of XAES spectra for various LMM Auger transitions of pure Cu (L3M45M45, L3M23M45, L3M23M23 and L2M45M45 transitions). We compare the resulting primary excitation spectra with theoretical results published in the literature and obtain reasonable quantitative agreement.

They also note the distinctive Cu L 3 M 4,5 M 4,5 peak at 916.5 eV for Cu 2 O. Poulston et al. [3], in their study of surface oxidation and reduction of Cu 2 O and CuO, have used both the Cu LMM and the Auger parameter to distinguish Cu (0), Cu (I) and Cu (II).

a) Cu 2p XPS, b) Cu LMM Auger, and c) I 3d XPS spectra of Cu, CuI, and Cu-CuI electrodes after CO 2 RR. [...] A Cu-CuI composite catalyst achieves a remarkable C2+ partial current density of...

2021年12月10日 · Herein, we fabricate the SMSI between sputtering reconstructed Cu and flame-made LaTiO 2 support at a mild reduction temperature, exhibiting an ultra-stable performance for more than 500 h at 600...
