Abstract

Pt–WO3−x catalysts showed very high catalytic activity in complete hydrodeoxygenation (HDO) of vanillin, a typical model compound of lignin, affording methylcyclohexane (MCH) in 92.5% yield at 220 °C, under 4.0 MPa H2 and in 2 h in n-hexane as the solvent. By tuning the reduction time and pre-treatment of the WO3 support, the influence of Pt species and oxygen vacancy sites of Pt–WO3−x on vanillin HDO performance was analyzed. The reaction pathway of vanillin HDO over Pt–WO3−x was proposed. Moreover, Pt–WO3−x showed wide applicability to the HDO of other phenols and high catalytic stability.
