Highly dispersed copper nanoparticles supported on combined alkaline-earth metal oxides MgO-CaO and MgO-SrO were synthesized by impregnation-combustion method and used for hydrogenolysis of glycerol. The nanoparticles were characterized using N2-adsorption
X-ray diffraction
transmission electronic microscope
temperature-programmed reduction with H2
dissociative N2O adsorption and CO2 temperature-programmed desorption. The results revealed that Cu particles dispersed highly on the surface of Cu/MgO-CaO and Cu/MgO-SrO catalyst. The enhanced alkalinity of Cu/MgO-CaO and Cu/MgO-SrO accelerated the conversion of glycerol compared to Cu/MgO. It was concluded that the activity of Cu-based catalyst increased with its alkalinity.
