WITHDRAWN CO2 Methanation over Olivine-Supported Nickel Catalysts

Ni/olivine with low nickel loading showed excellent CO₂ methanation activity and stability. The interaction between NiO and the thermal induced high dispersed reducible FeO_x during reduction leads to the formation of Ni-Fe alloy. Redox property of the support could greatly affect the catalytic activity, restrict sintering and deactivation by carbon-deposition.
