Thermally stable Ni foam-supported inverse CeAlOx/Ni ensemble as an active structured catalyst for CO2 hydrogenation to methane

Abstract Nickel is the most widely used inexpensive active metal center of the heterogeneous catalysts for CO 2 hydrogenation to methane. However, Ni-based catalysts suffer from severe deactivation in CO 2 methanation reaction due to the irreversible sintering and coke deposition caused by the inevitable localized hotspots generated during the vigorously exothermic reaction. Herein, we demonstrate the inverse CeAlO x /Ni composite constructed on the Ni-foam structure support realizes remarkable CO 2 methanation catalytic activity and stability in a wide operation temperature range from 240 to 600 °C. Significantly, CeAlO x /Ni/Ni-foam catalyst maintains its initial activity after seven drastic heating-cooling…
