Copper promoted Co/MgO: A stable and efficient catalyst for glycerol steam reforming

Abstract Different types of cobalt-based mixed oxide catalysts (20 wt%Co/MgO, 5 wt%Cu-20 wt% Co/MgO, 20 wt%Co/50%MgO–50%Al2O3) were synthesized by the co-precipitation method and applied for hydrogen production from glycerol steam reforming. The catalysts were characterized using X-ray diffraction (XRD), H2-Temperature-programmed reduction (H2-TPR), CO2-Temperature Programmed desorption, CO-Chemisorption, and CHN techniques. The H2-TPR analysis showed the reducibility of cobalt-oxide (5Cu20CM; 5 wt%Cu-20 wt% Co/MgO) was enhanced by the copper, and reduction profiles of cobalt oxide shifted to a lower temperature (
