摘要：

Nickel (Ni), iron (Fe) and three series of Ni-Fe bimetallic catalysts supported on alumina and silica were tested for the CO2 hydrogenation reaction at 448-548 K. The supported Ni-Fe catalysts containing 75 wt.% of the total metal loading as Ni and 25 wt.% as Fe showed a significantly better CO2 conversion and higher methane (CH4) yield compared to the Ni and Fe supported catalysts. Furthermore, the enhancements of conversion and yield were higher for the alumina supported catalysts than for the silica supported catalysts. The enhancements appear to be independent of total metal loading. It appears that the enhancements of conversion and yield were due to the formation of a suitable Ni-Fe alloy, and/or increase in the number of metal sites, and/or the availability of adsorbed CO2 species.
