A series of Pd catalysts were prepared on different supports (Fe2O3, SiO2, ZnO, MgO, Al2O3, carbon, and Amberlyst-45) and used in the selective hydrogenation of phenol to cyclohexanone in water. The Amberlyst-45 supported Pd catalyst (Pd/A-45) was highly active and selective under mild conditions (40–100 °C, 0.2–1 MPa), giving a selectivity of cyclohexanone higher than 89% even at complete conversion of phenol. Experiments with different Pd loadings (or different particle sizes) confirmed that the formation of cyclohexanone was a structure sensitive reaction, and Pd particles of 12–14 nm on Amberlyst-45 gave better selectivity and stability.
