Therefore, the presence of a NiIII center was further confirmed by X-ray photoelectron spectroscopy (XPS), which shows an increase of the Ni 2p3/2 and 2p1/2 binding energies of ~1.5 eV for 5 versus 4, demonstrating the presence of a more oxidized Ni center (Supplementary Fig. 60)54...
The chemical environments of the synthesized Ni-based catalysts were studied by X-ray photoelectron spectroscopy (XPS). Supplementary Fig.5shows the high-resolution Ni 2pXPS spectra. For Ni/C, the peak at 852.1 eV was assigned to the Ni(0) species, and the peaks at 853.6 and 855.2...
XPS was used to characterize the composition of the resultant surfaces, while the surface morphology was examined using AFM [71,72]. Nanoindentation was used to examine the mechanical properties of the films [71]. XPS revealed that the only N compound formed in the nitrogen- implanted specimens...
其实XPS峰位置与电子环境有很大的关系,3价Ni一般会与2价Ni共存,会表现为两个峰(854-856之间)...

X-ray spectroscopy is highly convoluted by mixed oxides with various oxidation states, making it difficult to uniquely identify the subspecies resolved by the simulations. Nevertheless, we can verify the qualitative agreement between experiment and theory using XAS in addition to the XPS data already ...
Detailed analysis of XPS shows that nZVI can remove Ni(II) through adsorbing Ni(II) on the surface of nZVI and then reducing it to low-toxic Ni(0) as presented here [209]: (6.20)☰FeOH+Ni2+→☰FeO-Ni++H+ (6.21)☰FeO-Ni++H2O→☰FeONi-OH+H+ (6.22)☰FeO-Ni++Fe0+...
