Intensities of 蟺-蟺* shake-up satellite of the C 1s XPS peak have been measured, and the results were consistent with those of NEXAFS. Smaller concentrations of CC double bonds can be attributed to the incomplete dehydrogenation due to the relatively low temperature of the CVD treatment. High...
C) The O 1s and Mn 2p XPS spectra of Mn3O4-xbefore and after adsorption of Li2S6. (D) The absorption energy of Li2S6on the (103) plane of Mn3O4and Mn3O4-x, respectively. (E) Cycling stability of Li|...
The deconvolution of the O 1s region of the XPS reveals that the doping treatment does not increase the surface oxygen percentage of the CB (Table 1). However, differences in bonding arrangements were found, and they mainly lie on a higher amount of surface carboxylic groups (see Table S2)...
Interpretation of XPS spectra C-C peak at 284.8eV is frequently used a charge correction reference because of its convenience. Not always reliable, possibly changing with nature of the surface hydrocarbon, film thickness and nature of the sample. C1s spectra for polymers tend to have...
(2) In case of GO, the ration of (C=O) tosp2graphitic structure is very large (XPS of C 1s), however, for CPE-QDs this ration is not so large, and (3) Oxidized graphite/GO have very narrow PL spectra, unlike to the CPE-QDs’ broad PL peak observed in the present report42,...
Here %Cis the percent of the atomic carbon and %sp2area ratio from C 1sfittingis the percent of the peak area ofsp2from the C 1sdeconvolution result. The fraction of OCFGs (%) was calculated from the XPS data (Eq.2) $${{{\rm{OCFGs}}}\,{({\%})}{=}\frac{{{\%}}_{{C}}...
FIG. 7: Pairs of high-resolution C1sXPS spectra for (a) sample 1 (with H2O2), (b) sample 2 (with DMS), (c) sample 3 (with NaBH4), and (d) Ctrl sample. The bottom half of each figure pair in each section shows the curve fittings to the C1s peak. The spectra are fitted to...
(FIG. 11). XRD is consistent with a wurtzite structure for the crystallites. A signal contribution from zinc blende stacking faults or individual zinc blende particles is also possible. From XPS measurements, the C 1s high-resolution peak displays asymmetry, including a pronounced contribution from...
In addition, the high-resolution O 1s spectrum was divided into three chemical bonds, C-Ti-OH, C-Ti-Ox and O-Ti-O, whose peak centers were located at 532.7, 529.6 and 530.6 eV, respectively [44], [45]. The high-resolution XPS spectra of the other two composite films were recorded ...
X-ray photoelectron spectroscopy (XPS) was then used to characterize these carbon nanomaterials. As shown in Figure 2, the dominant graphitic C 1s peak at 284.8 eV and O 1s peak at 532 eV were observed for three carbon nanomaterials, and N 1s peak around 400 eV could be detected for ...
