1. Synthesis and Oxygen Storage Capacity of Two-Dimensional Ceria Nanocrystals，Angew. Chem. Int. Ed. 2011, 50, 4378 –4381 we have developed a facile, robust synthetic method to prepare 2D ceria nanoplates, which have high theoretical surface-area-to-volume ratio and desirable (100) surfaces. For these reasons, the ceria nanoplates exhibit much higher OSC than the 3D ceria nanomaterials prepared by combustion and hydrothermal methods. With these superior properties, our ceria nanoplates are also promising for many other catalytic applications. 2. Mineralizer-Assisted Shape-Control of Rare Earth Oxide Nanoplates，Chem. Mater. 2014, 26, 6328−6332 Rare earth oxides are important emerging materials because of their unique properties. Nanosized, two-dimentional (2D) materials have received increasing attention due to their high surface-tovolume ratios and ultrathin layered structures. Here, we synthesize 2D rare earth (RE) oxide nanoplates in the presence of a mineralizer. The use of a mineralizer not only facilitates the synthesis of RE oxide nanoplates (i.e., increases the yield and allows mild reaction parameters), but also allows for shape-control. To emphasize the importance of RE oxide nanoplates in materials science and engineering, we demonstrate that (1) ceria nanoplates can be used in a ceria/Cu inverse catalyst to enable an enhanced CO oxidation activity, and (2) Y2O3 nanoplates doped with Eu3+ enable photon energy down-conversion. |
