The XPS Spectra section provides raw and processed survey spectra, chemical state spectra, BE values, FWHM values, and overlays of key spectra. Atom% values from surveys are based on sample, as received, and Scofield cross-sections. Atom% values are corrected for IMFP and PE. Peak-fits are guides for practical, real-world applications.

2018年1月1日 · X-ray photon spectroscopy (XPS) was analysed for non-treated and AuCl 3-doped graphene. The C 1s peak, corresponding to sp 2 C − sp 2 C bond at ∼284.9 eV was not changed with heat treatment up to 140 °C.

2013年10月1日 · AuCl 3 is the electron donor in the adsorption process of hydrogen chloride. Thus, an increase in the Au 3+ electron density strengthened the bond between hydrogen chloride and AuCl 3. X-ray photoelectron spectroscopy (XPS) was used to identify the effects of the N-doped support and the electron state of Au 3+. The adsorption capacity of the ...

2022年5月1日 · The XPS and TPR tests proved that the Au-S bond broke as the acetylene hydrochlorination reaction proceeded. The DFT calculation proved that the Au-S bond is the active site, and the sulfur atom promotes the adsorption of C 2 H 2 by the catalyst.

2011年1月5日 · The X-ray photoelectron spectroscopy (XPS) analysis revealed that the doping level of the CNT film was strongly related to the amount of adsorbed chlorine atoms. Annealing at temperatures up to 200 °C did not change the amount of adsorbed Cl atoms on the CNTs, and the CNT film was stable under ambient conditions.

2024年2月29日 · The X-ray photoelectron spectroscopy (XPS) measurements were performed on the WSe 2 w/o and w/ AuCl 3, respectively, to confirm the presence of AuCl 3 dopants on the WSe 2 channel, as shown in...

XPS Spectra Gold (Au) Compounds The XPS Spectra section provides raw and processed survey spectra, chemical state spectra, BE values, FWHM values, and overlays of key spectra.

The 0.6AuCL sample, which contains mainly oxidized gold species as identified by XPS in Fig. 4, by FTIR in Fig. 2, and by H 2 -TPR in Fig. 5, has a much higher light-off temperature than the...

TiO2 impregnated with AuCl3 was subjected to different pretreatments and then characterized by XPS and DRS. After drying at 298 K under vacuum, the catalyst contains highly dispersed, nonmetallic Au species; whereas drying at 393 K in an oven caused the Au to be partially reduced and agglomerate.

2010年2月1日 · The TEY XANES and XPS spectra implied the formation of predominant polysulfide species and metallic gold, while the transmission spectra showed Au–S bonding, the share of which increased with increasing molar Na 2 S/HAuCl 4 ratio in the reaction solution.
