Influence of the Ni/Co ratio in bimetallic NiCo catalysts on methane conversion into synthesis gas

Abstract

Mesoporous NiCo–Gd0.1Ti0.1Zr0.1Ce0.7O2 catalysts with a variable Ni/Co ratio were synthesized by co-precipitation with sonication. The catalysts exhibited high activity and selectivity for synthesis gas production by CH4–O2 and CH4–CO2 reforming at 850–950 °C. The catalyst with 80Ni/20Co demonstrated the best results in the partial oxidation and dry reforming of methane.
