代表分峰拟合的时候,将Fe 2p的强谱峰分成了浅红色的Fe(Ⅱ)峰和浅绿色的Satellite峰。Satellite的英文意思是卫星,即浅绿色的峰代表的是卫星峰,也就是小的伴峰的意思。(常规X射线源(Al/MgKα1,2)并非是单色的,而是还存在一些能量略高的小伴线(Kα3,4,5和Kβ等),所以导致XPS中,除Kα1,2所激发的主谱...
S2b) exhibits the typical XPS feature of Fe 2p (III) which shows the signals of Fe 2p1/2 and Fe 2p3/2 at the binding energies of 713.2 and 726.7 eV with their corresponding satellite peaks at 721.1 and 735.6 eV arising from the charge transfer screening32. Only very weak ‘...
50、s. In addition, there appears to be another satellite peak at 729.5 eV; this may be a satellite peak for Fe 2p1/2. The XPS spectrum of Fe 3p for the Fe2O3standard sample is shown in Fig. 6. Although the Fe 3p peak consists of both Fe 3p3/2and Fe 3p1/2, a single peak...
In addition, the Fe 2p3/2peak of Fe-CDs was accompanied by an adjacent characteristic satellite peak, which was ascribed as the oxidized ionic form of Fe [48]. This was possibly due to the oxidation of Fe ions in the raw precursor caused by the high temperature and oxygen ambience from...
In Fig. 4f, the Fe 2p displays two main peaks, Fe 2p3/2 at 712.09 eV and Fe 2p1/2 at 725.32 eV. The deconvolution of Fe 2p3/2reveals two bands at binding energies of 711.22 and 713.88 eV with a satellite peak near 720.12 eV43. Fig. 4 XPS of Fe-Co-P-O-50: (a) survey ...

XPS spectra of Fe-CoP and CoP catalysts in b Co 2p3/2; c Fe 2p3/2 and d P 2p regions. e Polarization curves of the CC, Fe-CoP/CC and CoP/CC for FDMOR (scan rate of 5 mV s−1; electrolyte: 1 M KOH; FDM concentration: 100 mM) Full size image...
Figure 3d further shows the Fe 2p spectrum, where the binging energy peaks at 723.9 and 710.8 eV match well with the Fe 2p1/2 and Fe 2p3/2 levels, respectively, confirming the existence of pure Fe3O4. The typical satellite peaks at 729.5 and 719.0 eV have not been ...
due to the surface oxidation of the sample. Peaks at binding energies of 715.8 and 728.9 eV are satellite peaks. The existence of Fe3N is also supported by the Raman spectrum in Supplementary Figure5, in which peaks at 211, 280, and 383 cm−1are assigned to Fe3N according to ...
It was also observed that the difference in energy between a high-spin iron 2p 3/2 peak and its corresponding shake-up satellite peak increased as the electronegativity of the ligand increased. The extrinsic loss spectra for ion oxides are also reported; these are as characteristic of each ...
