Adventitious carbon contamination is commonly used as a charge reference for XPS spectra. C1s spectrum for contamination typically has C-C, C-O-C, and O-C=O components. The C-C component may be set to a binding energy of 284.8eV, by default.

Jul 21, 2020 · The carbon species and banding energies for several typical kinds of carbon materials (graphite, carbon black, graphene, carbon nanotubes, carbides, and polymers) were summarized with typical XPS spectra.

X-ray photoelectron spectroscopy (XPS or ESCA) curve fitting procedures, reference materials and useful notes are listed here to provide a starting point for the consistent interpretation of XPS spectra.

Apr 1, 2014 · X-ray photoelectron spectroscopy (XPS) has been commonly used to determine the nitrogen-containing functional groups of graphene. However, reported assignments of C1s shifts of nitrogen-containing functional groups are unclear. Most works discuss peak shifts of only N1s spectra and C1s shifts and the full width at half maximum (FWHM) are excluded.

A review on C1s XPS-spectra for some kinds of carbon materials

Jul 21, 2020 · The adsorption of carboxyl groups on the surface of BaTiO 3 nanoparticles can be determined by the peak of 289 eV in the XPS spectrum of C 1s, which belongs to carboxyl groups (as shown in...

High-resolution XPS O 1s spectra obtained from Pd 80 In 20 /HAp displayed two deconvoluted peaks at binding energy of 530.8 and 532.4 eV associated with C]O and OeC]O [75] (Fig. 3c). ...

Apr 2, 2013 · Several simple methods are presented and evaluated to simulate the X-ray photoelectron spectra (XPS) of organic monolayers and polymeric layers by density functional theory (DFT) and second-order Møller–Plesset theory (MP2) in …

Jan 1, 1988 · Line shape analysis of the XPS C1s spectrum is found to provide good parameters for evaluating the degree of graphitization on a carbon fiber surface. A narrower and a more asymmetric C1s spectrum is shown to correspond to a more complete graphite lattice structure.

The XPS spectra (Fig. 1d) showed a single peak at 281.4 eV corresponding to the C1s transition. The singularity of the peak shows good purity of the prepared C 60 [41].
