Abstract: The redox properties and oxygen buffering capacity of reducible oxides, such as ceria, make them interesting support materials for oxygen carriers in Chemical Looping Combustion (CLC), an emerging clean combustion technology. However, the effectiveness of reducible oxides for redox applications depends crucially on oxygen mobility in the oxide lattice. In the present work, we demonstrate that addition of an aliovalent dopant (La) strongly enhances oxygen mobility in ceria, resulting in multiple performance benefits.
