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

Mesoporous NiCo–Gd_0.1Ti_0.1Zr_0.1Ce_0.7O₂ 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.
