Ni/TiO2 Catalysts Supported with Al2O3 Over CO2 Reforming

摘要

The 5 wt % Ni/TiO2-Al2O3 xerogels catalyst was prepared by the sol-gel synthesis of titanium n-butoxide in methanol with nickel and aluminum. X-Ray diffraction, TG/DTA and SEM were used to characterize the function of addition aluminum to Ni/TiO2 catalyst. The role of aluminum addition promotes the formation of large metallic Ni ensembles increase the dispersion of Ni, suppression of Ni/TiO2 catalyst deactivation and carbon deposition.
