Trade‐offs in stability and activity: A study of ordered mesoporous alumina and γ‐Al2O3 supported Ni catalysts for CO2 methanation

The Canadian Journal of Chemical Engineering, EarlyView.
CO2 methanation over Ni‐K alumina catalyst synthesized via evaporation‐induced self‐assembly to prepare ordered mesoporous alumina (Ni‐K‐OMA) catalysts and via incipient wetness impregnation (Ni‐K/Al2O3). Ni‐K‐OMA exhibited higher CH4 selectivity while Ni‐K/Al2O3 had a higher TOF.
