Oxygen vacancy-dependent low-temperature performance of Ni/CeO2 in CO2 methanation

The transformative power of CO2 methanation can efficiently transform greenhouse gases into high-value products, aligning with the carbon neutrality goals. However, achieving this target at low temperature requires cumbersome efforts in designing catalysts that possess high reactivity and selectivity. Focusing on understanding the pivotal role of alkaline (such as Ca) sites in catalyzing these reactions…
