“…As reported by Teles et al., the effect of metal type for the phenol hydrogenation was investigated over silica supported catalysts. Multiple catalysts, such as Pd, Pt, Ru, Rh and Ni, have been developed so far for this reaction. Particularly, Pd exhibits excellent selectivity and activity for phenol hydrogenation in the aqueous phase.…”

Metal‐organic frameworks (MOFs) have been extensively applied as supports in hydrogenation catalysis owing to their topological structure and high hydrogen storage capabilities. Pd nanoparticles (NPs) supported on a hollow box‐shaped MOF were prepared for phenol hydrogenation in the aqueous phase. The MOF preparation modulated by monocarboxylic acids grow into different structures. MOF140‐AA, modulated by acetic acid at 140 °C, presents the structure of regular cube with a smooth surface. Compared to other supports, Pd NPs supported on MOF140‐AA presents high phenol conversion due to the high hydrogen storage capability of MOF140‐AA. Phenol is completely converted to cyclohexanol over Pd/MOF140‐AA reacted at 260 °C for 2 h with high selectivity. The reaction mechanism of phenol hydrogenation is studied by density functional theory (DFT). The phenol hydrogenation mechanism is calculated on a Pd38 cluster, which describes the reaction pathway consistent with experimental results.

“…Consequently, the metal‐π interaction between Pd and MIL‐101 was created, and the catalytic activity was improved . Moreover, MIL‐101 supported Ru NPs was prepared via gas‐phase infiltration of Ru‐(cod)‐(cot) (cod: 1,5‐cyclooctadiene; cot:1,3,5‐cyclooctatriene) by Ertas and coworkers (Figure ) . In comparison with Ru‐based catalysts reported previously, Ru/MIL‐101 prepared by this method had a more remarkable selectivity of cyclohexanone (90%) with a 90% phenol conversion.…”

The selective hydrogenation of phenol to cyclohexanone has attracted a great deal of attention both in industry and academia. In this review, the significance, strategies and mechanisms for the production of cyclohexanone are briefly described. Then, the evolution of phenol hydrogenation in gas/liquid phase is summarized according to catalyst type. In situ hydrogenation techniques including catalytic transfer hydrogenation (CTH) and electrocatalytic hydrogenation (ECH) of phenol are also discussed. Although the technology for catalyst design has developed rapidly within the past decades, direct evidence to understand the reaction mechanisms and kinetics is still scarce. Therefore, it is still challengingto explore the function mechanisms and design advanced catalysts with high activity and high selectivity (>95%) for direct hydrogenation of phenol to cyclohexanone. This review may provide guidance for these attempts.

“…32 This is surprising, given the extensive efforts to develop MOFs for hydrogen storage, their well-known hightemperature stability, and reports showing that a number of MOFs are stable in the presence of reducing agents such as metal hydrides. 33,34 There are now a few reports in which MOFs serving as supports for transition metal nanoparticles to catalyze hydrodeoxygenation, hydrogenation, and hydrogenolysis, 32,[35][36][37][38][39][40] but the MOF itself does not appear to be the agent directly responsible for the hydrogenolysis. In one case, the reaction was conducted in liquid water 36 and tandem catalytic behavior has been observed using the metal-loaded MOF.…”
