2020年11月20日 · Ni/NiO catalyst exhibits superior HER activity compared to Ni or NiO bare. In situ raman shows that Ni/NiO maintains Ni (OH) 2 species initially during HER. Nickel/Nickel oxide (Ni/NiO) nanosheets heterostructure is a cheap and active catalyst for hydrogen evolution reaction (HER) in alkaline electrolytes.

XPS Signals for Nickel, (Ni o) Metal. Spin-Orbit Term, BE (eV) Value, and Scofield σ for Aluminum K α X-rays (1486 eV, 8.33 Ang)

XPS 光谱解读. Ni2p 峰具有明显的自旋轨道分裂峰 (Δ 金属 =17.3 eV)。 镍金属谱图的峰形复杂。 主峰与卫星特征峰混杂。 Ni金属的卫星峰不要和氧化镍的峰混淆了。 镍化合物也可能具有复杂、多重劈裂的峰形。

2022年11月2日 · The present work is directed toward resolving the origin of main and satellite features for the Ni 2p XPS of NiO based on ab initio molecular orbital wave functions (WFs) for a cluster model of NiO. A major problem in earlier ab initio XPS studies of ionic compounds has been the use of a common set of orbitals that was not able to properly ...

2006年5月1日 · A current interpretation of XPS spectra of Ni metal assumes that the main 6 eV satellite is due to a two hole c3d 9 4s 2 (c is a core hole) final state effect. We report REELS observation in AES at low voltages of losses (plasmons and inter-band transitions) corresponding to the satellite structures in Ni metal 2p spectra.

Atomic layer deposition (ALD) provides a promising route for depositing uniform thin-film electrodes for Li-ion batteries. In this work, bis (methylcyclopentadienyl) nickel (II) (Ni (MeCp) 2) and...

Surface morphology was examined using scanning electron microscopy (SEM), and the presence of Ni, Fe, and O was confirmed using energy dispersive x-ray spectroscopy (EDS).

2020年10月1日 · Principal component analysis (PCA) was conducted to analyze XPS spectra comprising NiO, TiO2, and NiTiO 3. The PCA could provide the accurate ratio of NiTiO 3 and NiO from the complex-shaped Ni 2p spectra. The PCA results of Ti 2p spectra inaccurately predicted the ratio of NiTiO 3 and TiO 2.

2012年11月30日 · NiO has been analyzed by X-ray diffraction (XRD), X-ray absorption fine structure (XAFS) analysis, and X-ray photoelectron spectroscopy (XPS) for bulk-scale and nanosized polycrystalline samples.

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.
