2025年1月17日 · High-resolution XPS spectra of Ni 2p (Fig. 1g) and Mo 3d (Fig. 1h) of Y-NiMo/MoO 2−x illustrate a shift towards higher binding energies with the addition of yttrium.

2022年5月27日 · Herein, we report an outstanding catalyst (Ni 0.2 Mo 0.8 N/NiMoP 2 /MoO 2 @NC) consisting of NiMo-based nanorod arrays supported on Ni foams for the efficient alkaline HER. It shows an ultralow overpotential of 48 mV and remarkable longevity for over 145 h at 10 mA cm –2 in 1.0 M KOH.

From the XPS spectra (Fig. 8C–E), it is found that both the Ni 2p peaks and Mo 3d peaks in Co(OH) 2 /NiMo CA@CC are shifted by 0.4 and 0.5 eV toward the lower binding energy relative to those of NiMo@CC, respectively, while the characteristic peaks of Co 2p are shifted toward high binding energy by 0.8 eV , indicating the transfer of ...

2020年11月5日 · Systematic investigations such as XPS, XAFS, and UPS reveal that the nitrogen incorporation effectively regulates the electron density and steers d-band center of NiMoS, which endows N-NiMoS with excellent HER activity.

High-resolution XPS of (a) Ni 2p and (b) Mo 3d. from publication: In Situ Evolved NiMo/NiMoO4 nanorods as bifunctional catalyst for overall water splitting | Due to their good conductivity and...

2023年2月1日 · The surface elemental composition and valence states of NiMoO 4 @NF and NiMo@NF-550 catalysts were analyzed by XPS spectra. The Ni 2p spectra of NiMoO 4 @NF precursors have two pairs of deconvoluted peaks corresponding to the Ni 2p3/2 and 2p1/2 peaks.

2019年8月10日 · 8月7日，清华大学深圳研究生院的杨诚研究团队在Advanced Functional Materials在线发表了题为“NiMo Solid Solution Nanowire Array Electrodes for Highly Efficient Hydrogen Evolution Reaction”的文章，报道了一种通过在水溶液中合成NiMo固溶体纳米线阵列的方法，得到的电极具有优异的析氢 ...

Mesoporous cobalt-nickel-zinc ternary oxide (CNZO) nanosheets grown on the nickel foam are prepared by a simple hydrothermal treatment and subsequent calcination process. The physical...

2024年4月26日 · The influence of Mo doping on the catalyst structure, reducibility, and electronic properties was investigated through a series of characterizations, including SEM, TEM, XPS, H2-TPR, and NH3-TPD. This study revealed that the ZIF-8 support with incorporated Ni and Mo maintained a stable structure.

XPS结果表明(图3A和B)，随着Mo原子的加入，Ni0峰值（单金属Ni为852.8 eV）在NiMo alloy中移至852.5 eV，在NiMo IMC中进一步移至852.3 eV，而Mo0峰值则向高结合能移动，说明Ni在NiMo alloy和NiMo IMC中的电负性增强，存在由Mo向Ni的电子偏移。...
