Polyhedral Shapes of CeO2 Nanoparticles
Abstract
Ceria nanoparticles are a widely used nanomaterial for applications in catalysts, fuel cell, and microelectronics. An important factor that influences the performance of CeO 2 is the particle shape. In this paper, a systematic study has been carried out to determine the shapes of CeO 2 nanoparticles. For particles in the size range of 3−10 nm, the particle shape is dominated by truncated octahedral that is defined by the {100} and {111} facets. The fastest growth of the nanoparticles along 〈100〉 results in the disappearance of the {100} facets; thus, the large size CeO 2 particles are dominated by the octahedral shape with flat surfaces. The nanoparticles agglomerate by minimizing the interface energy with the formation of a lattice matched “coherent interface”. The faceted shape also results in the textured distribution of nanoparticles deposited onto a substrate surface, with a preferred orientation of [110]. These structural characteristics are likely to affect their performance in technological applications.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
