In this work, ceria (CeO2) is incorporated into Ni-based mixed metal oxides (MMOs) obtained from hydrotalcites which are then put through the CO2 methanation process (250-400°C range). Ni-based materials were synthesized by coprecipitation, and ceria was incorporated into them using the reconstruction method. The structures were confirmed through XRD, TEM, BET, H2-TPR, and CO2-TPD analyses. Firstly, the effects of space velocity and Ni load on the catalyst were tested. 36000 h-1 and 5% of Ni were found to be suitable conditions for CO2 conversion. Adding Co or Fe to the Ni-based MMO was then evaluated. Co (but not Fe) improved catalyst activity. Afterwards, the role of CeO2 as a support on Ni-, NiFe- and NiCo-based MMOs was assessed. Selectivity and turnover frequency were enhanced in the materials without CeO2. Furthermore, due to the characteristics of CeO2, the MMO containing nickel, cobalt, and ceria was more stable, showing ~95% of CO2 conversion after 1400 min of continuous use.
