Fig. 3: Structural characterizations by XAFS.

From: Highly efficient recycling of polyester wastes to diols using Ru and Mo dual-atom catalyst

Fig. 3

Normalized XANES spectra: (a) Ru K-edge, inset: absorption edges of Ru; (b) Mo K-edge, Inset: absorption edges of Mo. R-space EXAFS spectra: (c) Ru samples, (d) Mo samples. EXAFS fitting: (e) Ru, (f) Mo of Ru-O-Mo. Inset: schematic diagram of the Ru4Mo1/TiO2 structure. 3D contour maps of WT-XAFS spectra: (g) Ru of Ru6/TiO2, (h) Ru and (i) Mo of Ru4Mo1/TiO2, and (j) Mo of Mo2/TiO2.
