Abstract

In this work, the Ru/MCM-41 catalyst prepared by chemical fluid deposition technique by using supercritical CO 2 as solvent exhibited high catalytic activity for aromatic hydrogenation of bisphenol A and benzyl alcohol. Supercritical CO 2 could provide the mobility for the Ru metal precursors to disperse and penetrate throughout the mesoporous silica support MCM-41. The characterizations of Ru/MCM-41 were performed by transmission electron microscopy (TEM), X-ray diffraction (XRD) and energy dispersive X-ray spectroscopy (EDS). On the other hand, water was found to be a suitable and green solvent for aromatic hydrogenation. Moreover, the addition of acid (CO 2 and acetic acid) and base (sodium hydroxide) in water could significantly enhance the reaction rate of benzyl alcohol and BPA, respectively.
