Abstract
Fe based catalysts are promising for hydrodeoxygenation (HDO) of lignin derived phenolics due to their high selectivity for aromatics. In this work, the reaction mechanism of m-cresol HDO on Fe catalysts and the kinetic consequence with Pd addition were elucidated by examining the effect of H2, H2O and m-cresol pressures on toluene formation rate on Fe and PdFe catalysts. A direct CO bond cleavage mechanism is proposed for HDO catalysis on both Fe and PdFe catalysts, while Pd provides a facilitated reaction pathway at the PdFe interface and therefore promotes the catalysis on Fe without changing the high selectivity towards aromatics.
Hydrodeoxygenation of m-cresol proceeds via direct CO cleavage over Fe surface and addition of Pd provide new sites for H2 activation and create faster reaction pathway. [Display omitted]
•HDO of m-cresol on Fe proceed via a direct CO cleavage mechanism.•Fe surface is dominated by OH* species under m-cresol HDO condition.•Pd addition to Fe created new H2 activation sites and facilitated OH* removal.•PdFe synergy via reaction between H activated on Pd and m-cresol activated on Fe.
