The high catalytic performance of the Cu–Mg-supported/silica catalyst was attributed to the copper dispersion and the existence of Cu + species and acidic sites. Glycerol hydrogenolysis was found to be highly dependent upon the acidity and reducing property of Cu–Mg-supported silica catalysts. It was found that MgO content influenced the activity of the Cu-supported catalyst. The synthesized catalysts were characterized by N 2 sorption, X-ray diffraction (XRD), temperature-programmed desorption of NH 3 (TPD-NH 3), temperature-programmed reduction of H 2 (TPR-H 2), X-ray photoelectron spectra (XPS), scanning electron microscopy (SEM), inductively coupled plasma optical emission spectroscopy (ICP-OES), CO chemisorption, Fourier transform infrared (FTIR), and IR analyses of absorbed pyridine. The copper seemed to significantly affect the C–C cleavage and C–O cleavage of glycerol for 1,2-PDO formation. The Cu catalyst with the base as a promoter showed the highest activity for glycerol hydrogenolysis reaction (glycerol conversion 89.5% and 1,2-PDO selectivity 92.1%). In the present study, bimetallic Cu–Mg-supported silica catalysts were prepared by a chemisorption–hydrolysis method with different loadings of copper/magnesium and used for glycerol hydrogenolysis for 1,2-propanediol (1,2-PDO).
