All XRD peaks of MoS2 crystallized at 1000 °C were well synthesized and matched well with the peak positions of a MoS2 single crystal. Supplementary Fig. 2a, b show the X-ray photoelectron spectroscopy (XPS) results of MoS2 annealed at 1000 °C. The binding energy of the peaks at ...
Whereas the characteristic peak of N1S, which belonged to PANI (401.6 eV), also shifted to 399.3 eV. The merger of characteristic peaks from two sets and the shift of orbital characteristic peaks suggested the presence of Mo–N interaction [46]. In contrast, the peak position of Mo 3d ...
R-space) for Pd–MoS2shows the disappearance of the first-shell Pd–Pd scattering peak at 2.51 Å in comparison with Pd foils, indicating that the Pd species are formed neither as metallic Pd nanoparticles nor as Pd clusters. A prominent peak centered at a much lower R position is ob...
X-ray diffraction (XRD) was performed to determine the crystal structure of the MoS2 electrodes. Compared with the Ag electrodes’ distribution on the (111) crystal plane, the Ag electrodes’ peak position distribution in the MoS2 electrodes did not shift, and the typical characteristic diffraction...
Additionally, the XRD patterns of the MoS 2 /G compo- sites show that the (002) diffraction peaks of the graphene nanosheets cannot be detected, 23 indicating that the graphene nanosheets do not stack during the hydrothermal process and annealing. More recently, Li ...
