High-resolution transmission electron microscopy (HRTEM), Raman spectroscopy, x-ray diffraction (XRD) and x-ray photoelectron spectroscopy (XPS) were used to characterize both the...

Metallic 1T-phase MoS2 is a newly emerging and attractive catalyst since it has more available active sites and high carrier mobility in comparison with its widely used counterpart of ...

2023年3月16日 · These include: scanning electron microscopy (SEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and Raman spectroscopy. Similarly, XPS and Raman spectroscopy are suggested for 2H or 1T MoS 2 phase confirmation. We provide guidance on the collection and presentation of MoS 2 characterization data. This includes how to ...

Improving charge transfer is the key to the performance of non-noble metal semiconductor-based surface enhanced Raman scattering (SERS) substrates. In this work, the O-incorporated 1T-MoS2...

2019年4月30日 · XRD result shows that the MoS 2 films are mixed metallic octahedral prismatic 1T- and trigonal prismatic bulk crystal 2H-phases. The I-V relationships show higher electrical conductivity for the films prepared at 400 °C and 450 °C than the films prepared at 425 °C.

2024年1月22日 · The powder X-ray diffraction (XRD) patterns of 1T/2H-MoS 2 and 2H-MoS 2 are shown in Fig. 1a. The XRD pattern of 2H-MoS 2 shows peaks at 2 θ values of 13.84°, 33.56°, and 59.08° which corresponds to the (002), (100), and (110) reflections, confirming the hexagonal phase of MoS 2 (JCPDS card no. 01-075-1539) with cell parameters a = 3.14 Å ...

2024年1月30日 · In the current work, MoS 2 film has been deposited by a simple and economical hydrothermal route in an alkaline solution in one pot. Raman and X-ray diffraction analyses verified the growth of the dominant 1T-phase, which provides more active sites on the film.

2021年4月20日 · Results show that few-layer MoS 2 (3–5 layers) with a 1T phase up to 48% can be synthesized in a 50% ethanol solvent. This MoS 2 is used to catalyse the hydrodesulfurization reaction of dibenzothiophene, and the target product conversion rate reaches 84.2%.

2023年10月15日 · The XPS spectra (Figure S15 a-c) and XRD patterns (Figures S15 d) of 1 T/2H MoS 2 /CC-40 before and after cycling show similar intensities and negligible peak shifting. These results consistently prove that the 1 T/2H MoS 2 /CC-40 has excellent electrochemical stability.

2023年1月1日 · Fig. S3 shows the X-ray diffraction (XRD) pattern of MoS 2 synthesized according to the temperature change. The weak and overlapped diffraction pattern of the 1T-metallic phase (002) plane at 10.56º [50], [51] was observed in the MoS 2-130 sample (Fig. S3).
