Figure 1. The characterization of sFe-1T/MoS₂. (A) XRD patterns; (B) Raman spectra; (C) High-resolution TEM image of sample S10; (D) XANES curves of Fe L₃-edge; (E) NEXAFS curves of Fe K-edge with Fe foil reference; (F) Fourier-transform (FT) k²-weighted NEXAFS spectra of sFe-1T/MoS₂ with Fe foil reference; Wavelet transform (WT) of k²-weighted NEXAFS spectra for (G) S2, (H) S5, (I) S10 and (J) S20 based on the mode of Morlet wavelet function (κ = 3; σ = 0.5) for the first coordination shells, where 1 ≤ (R+α) ≤ 3 Å and 2 ≤ k ≤ 10 Å^-1. XRD: X-ray diffraction analysis; TEM: Transmission electron microscope; NEXAFS: Near edge X-ray absorption fine structure; XANES: X-ray absorption near edge structure.
