Designing highly efficient and low-cost catalysts for conversion of renewable biomass into high value-added chemicals and biofuels is important and challenging. Herein, a non-noble Ni-Mn bifunctional catalyst supported on activated carbon (Ni-Mn/AC) was developed by an incipient wetness impregnation method. The catalyst was found to be economic and efficient for the selective hydrodeoxygenation of biomass-derived 5-hydroxymethylfurfural (5-HMF) to 2,5-dimethylfuran (2,5-DMF). The optimal Ni-Mn/AC (Ni/Mn=3) catalyst achieved 98.5 % 2,5-DMF yield with 100 % conversion of 5-HMF under mild reaction conditions of 180 °C, 2.0 MPa H2 for 4 h. Furthermore, the catalyst exhibited outstanding reusability and could be recycled eight times without loss of activity. The addition of Mn not only enhanced the reactivity of 5-HMF but also resulted in the dominant reaction pathway shift from the hydrogenation of the C=O bond to the hydrogenolysis of C-OH bond, which was attributed to the synergy of highly dispersed Ni metallic nanoparticles and moderate Lewis acid sites from MnOx as revealed by detailed characterizations. © 2022 Wiley-VCH GmbH.
