Efficient and Selective Hydrogenolysis of 5-Hydroxymethylfurfural to 2,5-Dimethylfuran by a Bimetallic Copper-Palladium Catalyst on a Carbon-Doped Boron Nitride Support

Graphical The article reports the CuPd/BCN bimetallic catalysts were prepared for the selective hydrogenation reaction of HMF. The 10Cu3Pd/BCN catalyst exhibited extremely strong catalytic activity and favorable recoverability under the combined action of Cu−Pd alloy and support. In the present world, 2,5-dimethylfuran (DMF), as a renewable liquid fuel, is valuable for maintaining ecological stability. Therefore, it is quite necessary to enhance the selectivity of DMF during the hydrodeoxygenation (HDO) of 5-hydroxymethylfurfural (HMF) to DMF. In this paper, a copper-palladium bimetal supported on carbon-doped boron nitride (BCN) catalyst was prepared as a class of catalyst for HDO. Notably, under the combined action of Cu−Pd alloy and support, the catalyst of 10Cu3Pd/BCN showed remarkable activity with high selectivity (99.2 %) for DMF. In addition, the packing and dispersion of the alloy particles by the carrier improved the cycling performance of the catalyst. Therefore, the selection of 10Cu3Pd/BCN as a catalyst for HDO has excellent application prospects.
