• [Display omitted] •Cu-Co bimetallic nanoparticles are coated with carbon layers.•Carbon layers over the nanoparticles protect them from deactivation.•Cu-Co@Carbon shows high selectivity in hydrogenolysis of HMF to DMF.•The catalyst is kept in good recyclability in six-run test. Cu-Co bimetallic nanoparticles coated with carbon layers have been developed through direct heating treatment of bimetallic oxide precursors incipiently deposited with polyethene glycol. The as-synthesized nanocatalyst performs excellently in chemoselective hydrogenolysis of 5-hydroxymethylfurfural to 2,5-dimethylfuran. The Co-based catalysts exhibit higher performance than Cu-based catalysts. Cu-Co@C (Cu: Co=1:3) shows the highest yield of 2,5-dimethylfuran (99.4%). Bimetallic nanocatalysts are detailedly characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). The bimetallic nanoparticles are entrapped by carbon shells that can protect them from oxidation and deactivation. The catalytic activity and selectivity are kept constant in a six-run recycling test. The synergistic effect between two metal components is helpful to enhance catalytic performance.
