Figure 10. (A) Schematic of Ru₁/LDH-V_III, Ru₁/LDH-V_II, Ru₁/LDH synthesis via defect engineering; (B) FT-EXAFS spectra of Ru₁/LDH-V_III/V_II, and refs (Ru foil, RuCl₃, RuO₂); (C) Electron transfer between Ru and NiFe-LDH (M_III/M_II vacancies or none); CO adsorption on (110) surfaces of Ru₁/LDH-V_III/V_II; in situ FT-IR of saturated CO chemisorption; (D) Aerobic oxidation of benzyl alcohol (chemical equation) and plots of conversion-time, TOF, and selectivity.
