摘要：

Small plate structure makes big difference: A facile synthetic method for high-quality ceria nanoplates enclosed by (100) facets involves the usage of a mineralizer. Compared to the 3D ceria nanomaterials prepared by combustion and hydrothermal treatment, the ceria nanoplates exhibit superior oxygen storage properties (see picture).
