Sulfur vacancy-rich MoS2 as a catalyst for the hydrogenation ... - Nature
2021年3月22日 · Here, we show that an in-plane sulfur vacancy-rich MoS 2 nanosheet catalyst can bypass such a restriction by on the one hand facilitating both CO 2 dissociation to surface-bound CO and O (CO* and...
EPR spectra of MoS2/C60 - Blinc - 2010 - Wiley Online Library
2010年9月21日 · The X-band electron paramagnetic resonance (EPR) spectra of MoS 2 /C 60 have been studied. A strong T-dependent g-shift and photoconductivity have been observed. The electronic state of molybdenum was found to be Mo 3+.

2017年3月6日 · Electron paramagnetic resonance (EPR) can be used to measure unpaired electrons on coordinatively unsaturated defective sites and can also reflect basal sulfur...
Atomic-scale evidence for highly selective electrocatalytic N−N ...
2020年11月30日 · Here, we identified the atomic-scale origin of SPET-driven selectivity on MoS 2 using continuous-wave electron paramagnetic resonance (CW-EPR), Raman, and pulsed 1 H/ 2 H electron−nuclear double-resonance (ENDOR) spectroscopy.
(A) EPR spectra of the as-prepared MoS 2-NS and commercial MoS 2 ...
Defective MoS2 electrode has shown superior properties for lead (II) removal, such as (i) great specific capacitance and (ii) low charge transfer resistance toward the enhanced adsorption...
Sulfur vacancy engineering of MoS2 via phosphorus incorporation …
2022年1月1日 · Electrocatalytic N 2 reduction reaction (NRR) serves as a promising approach for converting N 2 to NH 3 in a sustainable way to replace the energy-intensive Haber-Bosch process. MoS 2 -based electrocatalysts hold great potentials in catalyzing N 2 reduction due to their similarity with active MoFe-co in biological nitrogenase.
Synergetic Phase Modulation and N‐Doping of MoS2 for Highly …
2024年12月4日 · To further verify the effect of magnetic attraction and electron transfer driven by N-doping, we performed electron paramagnetic resonance (EPR) measurements, as shown in Figure 6b. In the EPR spectra of all three MoS 2, P-MoS 2 presents a g-factor at 2.001 originating from sulfur vacancies generated during the annealing process.
JACS:单原子空位缺陷引发MoS2高效析氢 - 材料牛
2020年2月23日 · 近日,北科大张跃院士与康卓副教授在JACS上发表了题为“Single-atom vacancy defect to trigger high-efficiency hydrogen evolution of MoS 2 ”的文章。 作者首先通过高通量计算,在一系列的MoS 2 析氢模型中初步确定了硫空位(S空位)在浓度和分布上的最佳状态。 为了实现这一目标,作者采用了一种简单、温和的过氧化氢化学刻蚀方法,在MoS 2 纳米片表面引入均匀分布的单S空位。 通过对刻蚀时间、刻蚀温度和刻蚀液浓度的系统调节,实现了S空位状态的 …
