Figure 2. X-ray absorption spectroscopy analysis. K-edge near-edge spectrum (XANES) of (a) Zn element, (b) V element and (c) Cu element for (Cu1/3 Zn2/3 )3 (OH)2 V2 O7 ·2H2 O (USP), (Cu1/2 Zn1/2 )3 (OH)2 V2 O7 ·2H2 O (ESP) and Zn3 (OH)2 V2 O7 ·2H2 O (ZnPV) samples. Fourier transform extended fine X-ray absorption fine structure (FT-EXAFS) of (d) Zn element, (e) V element and (f) Cu element for USP, ESP and ZnPV samples. Wavelet transform K-edge EXAFS of (g) Zn and (h) V element for USP and ZnPV samples.
