Morphology and Composition of Biomineralized Ceria and Ceria-Zirconia Nanocrystals

Ceria and doped ceria nanocrystals (NCs) are of major technological importance as active catalyst support materials, particularly for environmental applications and energy conversion systems. A decrease in ceria particle size may substantially facilitate defect formation, which will increase oxygen vacancies and enhance redox activity. Zirconium is commonly doped into ceria to improve its catalytic activity and thermal stability [1-3].
