Synthesis and evaluation as CO2 chemisorbent of the Li5(Al1−xFex)O4 solid solution materials: Effect of oxygen addition

β-Li5AlO4 and Li5(Al1−xFex)O3 samples were synthetized, characterized and evaluated as CO2 captors. Iron addition induced a higher CO2 chemisorption, in presence or absence of oxygen, in comparison to pristine β-Li5AlO4.320
