Temperature-dependent a CO2 conversion and b CH4 selectivity of the CeAlOx/Ni/Ni-foam, Al2O3/Ni/Ni-foam, CeO2/Ni/Ni-foam, Ni/Al2O3, and Ni/Ni-foam catalysts (reaction conditions: GHSV = 10,000 h−1, 160–300 °C CO2:H2:N2 = 18:72:10, P = 0.1 MPa); c Reaction orders with respect to H2 and CO2 for methane formation; d CH4 based apparent activation energy (Ea) of CeAlOx/Ni/Ni-foam, Al2O3/Ni/Ni-foam, Ni/Al2O3 and Ni/CeAlOx catalysts; e GHSV-dependent activities of CeAlOx/Ni/Ni-foam catalyst at 240 °C.
