Aryl‐Bridged Polysilsesquioxanes as Support for Aqueous Phase Catalytic Phenol Hydrogenation: Effect of Hydrophobicity and Organic Content of the Support
Abstract In this research, aryl‐bridged polysilsesquioxane (ABPS) an organosilica material is used as support to synthesize an efficient palladium (Pd) catalyst for catalytic hydrogenation of phenol to cyclohexanone and cyclohexanol. Techniques such as N 2 physisorption, NMR, IR, TEM, and CO chemisorption were employed to characterize the support. ABPS‐supported catalysts showed significantly better conversion than conventional inorganic silica supported catalyst‐ Pd/SBA‐15 and the commercial activated carbon‐supported catalyst Pd/AC. Superior performance of Pd/ABPS catalysts was attributed to the presence of organic groups in the support which improved Pd dispersion and phenol adsorption on the catalyst.
