The synthesis of urchin-like crystalline MoS2 with micron unit size and surface area of 25m2g−1 and its application for the catalytic hydrogenation and hydrodeoxygenation (HDO) of liquefied wood sample are reported. We observed significant increase of deoxygenation rate considering intensities of CO and OH band intensities in liquid phase IR spectra. Prepared catalyst exhibited higher activity compared to commercial MoS2 powder. Elemental analysis of organic phase after HDO revealed equal elemental compositions for both samples, with higher yield in case of urchin-like MoS2. Oxygen content decreased from 43.3% to 8.2% (wt.); residual phenolic oxygen is not removable with catalyst described. Observed catalytic performance may provide new solutions in terms of biofuel processing.
