In this research, a series of catalysts based on MoSe2 were synthesized by the hydrothermal method and used for the catalytic hydrogenation of alkali lignin for the first time. For 4wt.% NiSe2/MoSe2 catalyst, at 290∘C, under 2MPa H2 pressure for 1.5h, the conversion of alkali lignin and the yield of bio-oil reached 96.47% and 93.68%, respectively. In addition, the composition of the product (bio-oil) was analyzed via Fourier transform infrared (FTIR) spectrometry, gas chromatography-mass spectrometry (GC-MS) spectra, and proton nuclear magnetic resonance (1HNMR) spectra. Finally, our study demonstrated that those MoSe2-based composite catalysts can effectively degrade the biomass into bio-oil containing valuable chemical products.
