摘要：The catalytic conversion of 5-hydroxymethylfurfural (5-HMF) to value-added chemicals was quite vital for the conversion and utilization of biomass resources. The development of novel and efficient catalysts was of great significance. In this work, a series of tannic acid doped catalysts (Ni-Co/TA@C) were prepared by hydrothermal self-assembly method using lignosulfonate as a building block and coordinating with metal ions Ni2+ and Co2+. The effects of different preparation conditions and reaction conditions on the performance of the catalysts were investigated, and the optimal conditions for catalytic transfer hydrogenation were also explored. The results showed that the conversion of 5-HMF was 99.97% and the yield of 2,5-dimethyl furan (DMF) was as high as 87.10% with Ni2Co/TA@C as catalyst under mild reaction conditions (240 degrees C, 2 MPa N2, 4h). The surface morphology, surface area and composition of the catalysts were characterized in detail. The Ni2Co/TA@C catalyst had higher total acidity and larger amount of strong acid sites, which was conducive to highly selective catalytic transfer hydrogenation (CTH) of DMF, and the larger specific surface area also promoted the dispersion and loading of Ni and Co. This study provided some novel findings for the construction of catalysts for biomass conversion.
