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.

2024年4月1日 · In this work, 2D/2D heterojunction photocatalyst of Ni-MOF/BiOCl was fabricated by a self-assembly approach. Band structure analysis, in-situ X-ray photoelectron spectroscopy (XPS), as well as photo-irradiated Kelvin probe force microscopy (KPFM) collectively authenticated the S-scheme electron transfer mode in the Ni-MOF/BiOCl heterojunction.

2023年1月1日 · By fitting both branches of the metallic Ni 2p spectrum, it was possible to resolve two previously unreported satellite peaks in the Ni 2 p1/2 portion of the spectrum. For the partial oxidation of the nickel surface, we analyzed the Ni 2p, O 1 …

2024年11月12日 · A highly efficient photorechargeable supercapacitor device has been developed made of red carbon dots and Ni-doped MoS2. It shows excellent visible-light sensitivity and long-term stability. Developing photorechargeable electrochemical devices has become a new paradigm for addressing the efficient utilization of solar energy for renewable ...

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.

The Ni 2p spectra in Fig. 4(c) show four deconvoluted peaks, with two prominent peaks at 857.24 eV and 875.54 eV, corresponding to the Ni 2p 3/2 and Ni 2p 1/2, and two satellite peaks at...

The NiFe-MOF of Ni 2p XPS spectrum ( Fig. 2b) exhibits two distinct peaks corresponding to Ni 2p1/2 and Ni 2p3/2, with binding energies of 874.3 and 856.3 eV, respectively, representing the...

In this work, a distinctive approach was taken to use an electrochemical heterostructure sensor with chemically reduced nickel boride (Ni3B) nanoparticles anchored in two-dimensional (2D) layered...
