Figure 12. Zr K-edge X-ray absorption spectroscopy analysis of ZW-UiO-67-based glasses. (A) XANES spectra at the K-edge of the Zr atoms for derivatives of ZW-UiO-67·MSA and references; (C) Corresponding radial distance χ(R) space spectra from k³-weighted Fourier transform of χ(k)-function from the Zr K-edge EXAFS. Comparison spectra for ZW-UiO-67·TFSA and derivatives are shown in (B) and (D). Insets in (C) and (D) show the octahedral Zr₆O₄(OH)₄ node. Color codes: Zr, purple; O, red; H, light gray.
