2020年2月24日 · This study demonstrates a potentially scalable, solvent free and phase selective synthesis of uncapped α-NiS, β-NiS and α-β-NiS composites using nickel alkyl (ethyl, octyl) xanthate...

2017年1月15日 · The microstructure and chemical composition of as-prepared NiS was confirmed by means of SEM, TEM, XRD, BET and XPS. The SEM analysis results demonstrated that the NiS microflowers were composed of hierarchical nanoplates, and its surface was much rougher compared to that of Ni(OH) 2 templates after sulfidation.

2020年10月1日 · Benefiting from the large surface area, N-doping induced electronic effect and interfacial coupling and synergistic effect between NiS and NiS 2, the as-prepared N doped NiS/NiS 2 (N-NiS/NiS 2) heterogeneous catalyst can realize multifunctional catalysis for hydrogen evolution reaction (HER), oxygen evolution reaction (OER) and urea oxidation ...

In this study, we report on the synthesis and characterization of a 2D-2D nanosheets of NiCuInS2: In2S3/g-C3N4 (NCIS/CN) as a highly efficient photocatalyst for hydrogen production.

Ni2p 3/2 peak structures and binding energies reflect two energetic contributions. The major contribution is that associated with the electrostatic field produced by ejection of the Ni (2p) photoelectron, the minor contribution is the relaxation energy associated with filling unoccupied, conduction band 3d 9 and 4s Ni metal orbitals.

2023年8月26日 · The compositional structure and microscopic morphology of the synthesized NiS 2 /rGO composite were investigated by X-ray powder diffractometer (XRD), X-ray photoelectron spectrometer (XPS), scanning electron microscope (SEM), transmission electron microscope (TEM), Raman spectra (Raman) and nitrogen adsorption and desorption measurements.

The developed 3D hierarchical porous structure and high specific area of membrane matrix provide strong space for the exposure of NiS active sites, and the NiS nanolayers loaded in the membrane...

Ultrafine NiS 2 nanocrystals and their nano–microstructure demonstrate high pseudocapacitive Na-storage capability and thus excellent rate performance (355.7 mAh/g at 20.0 A/g).

最近在分析xps的谱图，有一些问题，望高人指点：1、关于结合能，感觉与标准谱图有偏差，是根据c1s峰进行校正还是主峰进行校正？ 2、下图中将第二个峰定义为卫星峰（859eV)，看到文献中有提到零价镍的峰面积占总面积的80%，卫星峰小于20%。

2024年6月24日 · In this work, we employ operando X-ray absorption spectroscopy and near-ambient pressure X-ray photoelectron spectroscopy to elucidate that NiS undergoes an in-situ phase transition to an...
