Download scientific diagram | X-ray absorption spectra of NiO. Oxygen K-edge (left) and Ni L-edge (right) XAS spectra for NiO prepared in different oxygen ambient, namely 0.01 Pa (black line)...
Ni and oxygen K-edge XAS investigation into the ... - ScienceDirect
2004年11月30日 · Ni K-edge X-ray absorption spectra (XAS) have been recorded at the BL7C1 beam line of Pohang Light Source (PLS). Si(3 1 1) monochromator crystal has been used with detuning to 70% in intensity to eliminate the high-order harmonics. The data have been collected in transmission mode with nitrogen gas-filled ionization chambers as detectors.
Comparison of Nanoscaled and Bulk NiO Structural and …
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.
Nickel L-edge and K-edge X-ray absorption spectroscopy of non …
A series of nickel dithiolene complexes Ni[S 2 C 2 (CF 3) 2] 2 n (n = −2, −1, 0) has been investigated using Ni L- and K-edge X-ray absorption spectroscopy (XAS).
Tunable magnetic anisotropy of antiferromagnetic NiO in (Fe)/NiO…
2023年3月24日 · We report on the magnetic properties of antiferromagnetic NiO(001) thin films in epitaxially grown NiO/MgO(dMgO)/Cr/MgO(001) system for different thicknesses of MgO, dMgO.
Implanting Ni-O-VOx sites into Cu-doped Ni for low ... - Nature
2020年6月1日 · Here, we show a Cu-doped Ni catalyst implanted with Ni-O-VOx sites (Ni (Cu)VOx) for alkaline HER. The optimal Ni (Cu)VOx electrode exhibits a near-zero onset overpotential and low...
Oxygen hole formation controls stability in LiNiO2 cathodes
2023年7月19日 · We propose that through a careful combination of experimental XAS and computational predictions of XAS spectra, it is possible to disentangle not only the Ni and O contributions but also the effects of charge states and local coordination environment.
XAS and RIXS at the Ni L3-edge a, XAS of NiO, LaNiO3, LaNiO2 …
Our neutron powder diffraction data show that, indeed, hydrogen occupies the centers of the Ni-O squares, and spectroscopic evidence from EELS and XAS suggests that Ni is reduced to the Ni+...
Characterization by XAS of NiO thin films prepared by pulsed …
2005年1月1日 · Further understanding of the electrochromic mechanism taking place in anodically colored nickel oxide was achieved by XAS. From EXAFS simulation we were able to determine the percentages of electrochemically active phases and confirm the dissolution of the oxidized one, which was previously assumed by electrochemical characterization.
Kinetics of formation of NiO nanoparticles by X-ray absorption ...
2007年5月1日 · We report the in situ X-ray absorption investigations to study kinetic formation on NiO nanoparticles growth. The effects caused in the initial stage of particles growth by different heating rates are investigated. XAS results show that the particles disorder appears for high heating rates and growth process is faster for low heating rates.
