 Abstract: In this report, we show that nanocrystalline pyrite and marcasite (FeS2), supported on SBA-15, aerosil SiO2, activated carbon or Al2O3, are precursors of highly active catalysts for the hydrodeoxygenation of dibenzyl ether into toluene. High yields of toluene (up to 100 %) were achieved in experiments performed at 250 °C under initial H2 pressure of 100 bar for 2 h. In the recycling experiments, results from XRD and XPS analyses indicate that a fresh surface, formed upon the chemical transformation of FeS2 into Fe(1−x)S, is responsible for the high activity and high selectivity achieved in the conversion of dibenzyl ether into toluene.
