Treasure OVE: The performance of doped ceria for CO 2 adsorption is investigated by oxygen vacancy engineering (OVE), that is, the formation and regeneration of oxygen vacancies. The doping and synthesis methods can be adapted to OVE, while reduction with hydrogen effectively restores the number of oxygen vacancies back to its original level. The regeneration characteristics of ceria and the catalytic conversion of adsorbed CO 2 at moderate temperatures are also explored.
