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 4 wt.% NiSe2/MoSe2 catalyst, at 290 ℃, under 2MPa H2 pressure for 1.5 h, 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.

In this research, a series of novel MoSe2/SrTiO3 heterostructures were successfully prepared by a two-step hydrothermal method. The samples were characterized by XRD, UV-Vis, SEM, TEM, EDS and XPS. Results showed that the degradation of MO under UV is better than that under the visible light. And, MoSe2 loaded on SrTiO3 under UV irradiation demonstrated a higher catalytic activity. The degradation rate of methyl orange was 99.46% for MoSe2/SrTiO3 under the optimum loading weight (0.1 wt.%). This is mainly because the combination of MoSe2 and SrTiO3 prevents electrons and holes recombination in SrTiO3 and · O2 - appears in the system. In general, MoSe2/SrTiO3 heterostructures have good environmental friendliness for photocatalytic degradation.
