Data Collection Settings for Palladium (Pd) Conductivity: Palladium readily develops a native oxide that is sensitive to Flood Gun – Differential Charging Possible – float sample recommended; Primary Peak (XPS Signal) used to measure Chemical State Spectra: Pd (3d 5/2) at 335 eV

Peak 5 centered at 534.3 eV is attributed to Pd (3p) in an oxidized (+2) state [44]. It should be noted that peaks from oxygen (1s) in PdO and Pd (3p) in a zero-valence state could be...

2022年5月25日 · In situ high-resolution Pd 3d X-ray photoelectric spectra (XPS) in dark and under light irradiation were then conducted to investigate the charge transfer direction (Figs. 3b and S7).

2003年1月31日 · Electron energy loss spectra (ELS) and X-ray photoelectron spectroscopy (XPS) data obtained from palladium powder catalysts used for complete methane oxidation have been obtained in this study in order to gain information about the Pd chemical state.

Use Pd3p 1/2, which does not overlap with O1s, as a guide for any peak fitting. Intensity and binding energy of Pd3p 3/2 peak is set by the Pd3p 1/2 peak, according to the spin-orbit splitting and ratio. Remainder of intensity under at Pd3p 3/2, energy can then be attributed to oxygen.

XPS通过照射样品表面，利用其发射的电子能量谱来分析样品的元素组成和化学状态。对于二价钯离子，其XPS谱图通常包括Pd 3d和Pd 3p两个主要峰位。 二、Pd 3d峰位分析。 Pd 3d峰位提供了关于钯元素的丰度和化学状态的信息。在二价钯离子的XPS谱图中，Pd 3d5/2和Pd 3d3 ...

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.

The most significant overlapping spectral features are the 3p peaks from zirconium, the 4d region of gold and some secondary auger features from the Mg KLL auger when using an aluminium X-ray source (1486.7 eV), so take care when analysing mixtures of these, you may potentially need to look at another Pd orbital (although this is complicated ...

2021年6月2日 · In this study, we conducted in situ near ambient pressure-x-ray photoelectron spectroscopy (NAP-XPS) in gas conditions with water and oxygen for hydrous Pd oxide, which is also known as palladium hydroxide (Pd (OH) 2) and it is the key component of the Pearlman's catalyst widely used for organic reactions.
