In all these materials, the sulphur atom environments are identical, corresponding to heterocyclic sulphur, 163.3 eV binding energy. Experimental binding energies are compared with those obtained using a charge-potential model from CNDO orbital calculations.Harry Marsh and Peter M.A. Sherwood and ...
Using XPS (X-ray photoelectron spectroscopy), the binding energy of Fe―O―C was measured. Heating under an argon atmosphere was carried out. Both samples showed quite different reaction behavior, though the temperature at the beginning of the reduction reaction was almost the same. From these ...
Interpretation of XPS spectra The C1s spectrum from a sample with high concentration of sp2 carbon will have a broad, asymmetric tail towards higher binding energy. One or more satellite features, several eV from the main C1s peak, will also be observed in samples with high sp2 co...
The binding energy of B1s in XPS for boron substitution in the carbon lattice shows a peak ranging between 186.9 and 188.8 eV [308]. Additionally, the various boron oxides and carbides (BC2O, BCO2, B2O3, and BC3) formed on the carbon surface have B1s peaks ranging from 189.0 to ...
X-ray photoelectron spectroscopy (XPS) was applied to investigate the phase composition and content of surface species. The binding energy peaks at 711.4, 710.3, and 708.5 eV in the Fe2p spectrum are correspondingly ascribed to FeIII, FeII, and Fe-C (Fig.4a)32. As for C1s spectrum, the...
(XPS).Figure 1(b)shows a typical broad-scan XP spectrum of the surface passivated SiNWs. The intense signals at 99 eV and 148 eV binding energy correspond to the silicon 2 p and 2 s electrons respectively. The signal at 284 eV corresponds to the C 1 s electron, which ...
The X-ray photoelectron spectroscopy (XPS) (Figs. 1c and S3) was performed, in a next step, to corroborate the presence of the aforementioned oxygen functional groups and meanwhile provide quantitative analysis. From the survey scans shown in Fig. S3, all samples are predominantly composed of ...
Carbon nitride thin films deposited by dc unbalanced magnetron sputtering have been analyzed by high-resolution X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy. The XPS data show that N 1s binding states depend on substrate temperature ( T s ). By comparison with the Raman spectra,...

The bonding arrangements of the doping elements on the carbon surface were assessed from the deconvolution of the XPS curves (Fig. S2) at the biding energy values summarized in Fig. S3, collected from the literature. The functional surface groups are given in Table S1. Three main bonding conf...
