Abstract
Abstract The conversion of lignin-derived phenolic compounds into high-value chemicals through value-added reactions holds significant importance. Cyclohexanol, an essential chemical raw material and organic intermediate, was synthesized in this study from guaiacol, a phenolic compound derived from lignin, through a hydrodeoxygenation reaction. When compared to mechanically mixed and supported catalysts, the use of the HZSM-5@Pd-SiO2 core-shell catalyst resulted in a cyclohexanol yield of 51.1% after a reaction conducted at 493K and 2 MPa H2 for 8h. The core-shell catalyst was characterized using TEM, N2 adsorption-desorption, and NH3-TPD, Py-FTIR revealing its rich acid sites, large specific surface area, and uniform mesopores.
