The catalytic conversion of alkali lignin to chemicals has been the subject of intense research efforts during the past few decades. In this study, VS₂ catalysts, with different morphologies of sheets and nanoflowers, were prepared through hydrothermal methods and applied to the hydrogenation of alkali lignin. The conversion of alkali lignin and yield of bio-oil are 77.02 and 58.75%, respectively, at 250 掳C under 2 MPa H₂ for 1.5 h with a VS₂ sheets catalyst, which is higher than that of a flower-like VS₂ catalyst. It was found that mainly the components of bio-oil were phenols, important and useful chemicals in transportation fuels and chemical industries. Our results indicated that the prepared VS₂ catalyst can be used as an effective material for degrading biomass to obtain valuable chemicals.
