Abstract It is challenging to elucidate the mechanism of CO2 methanation reaction over nickel-based catalysts and precisely tune the kinetics of rate-determining-step. In this work, we propose a strategy to engineer the oxygen vacancies of nickel-based catalysts for enhanced CO2 methanation. A Y2O3-promoted NiO-CeO2 catalyst is prepared and found to exhibit an outstanding methanation activity that is up to three folds higher than NiO-CeO2 and six folds higher than NiO-Y2O3 at mild reaction temperatures (
