Show your face, and we know what you do: CeO2 nanoshapes have been investigated to determine the exposed surfaces and internal defects. CeO2 rods and octahedra expose mainly (111) planes, whereas cubes are composed primarily of (100) facets. The nature of the exposed surfaces affects the activity in the water–gas shift reaction as well as the interaction of surface sites with CO.
