Enhancement of dry reforming of methane for syngas production over M/Mg1-XM’xO catalysts (M=Ni, Pd, and Pt., M’=Ce3+, Ce4+, and Ni2+)

Enhancement of dry reforming of methane for syngas production over M/Mg1-XM’xO catalysts (M=Ni, Pd, and Pt., M’=Ce3+, Ce4+, and Ni2+)

In this study, the conversion of methane and carbon dioxide to synthesis gas using dry reforming of methane over Ni, Pd, and Pt/MgO catalysts in different concentrations of Ce3+, Ce4+and Ni2+ was prepared via the co-precipitation of Mg and Ce nitrates, followed by impregnation with 1 wt.% each of Ni...
