Imaging the atomic surface structures of CeO2 nanoparticles.
Atomic surface structures of CeO2 nanoparticles are under debate owing to the lack of clear experimental determination of the oxygen atom positions. In this study, with oxygen atoms clearly observed using aberration-corrected high-resolution electron microscopy, we determined the atomic structures of the (100), (110), and (111) surfaces of CeO2 nanocubes. The predominantly exposed (100) surface...
متن کاملExploring the cytotoxicity of CeO2 nanoparticles: A compendious approach
Metal oxide nanoparticles due to their antioxidant properties have attractedsignificant attention and exhibited good potential for use in cancer theranostics.Owing to the poor absorption in the physiological environment, they are anideal candidate to act as nanocarriers in targeted drug delivery and bioimaging.This feature can be successfully implemented in live monitori...
متن کاملRelative stability and reducibility of CeO2 and Rh/CeO2 species on the surface and in the cavities of γ-Al2O3: a periodic DFT study.
We report the structure and stability of ceria units deposited on the surface of γ-Al2O3 or incorporated in its cavities, as determined by periodic density functional calculations. Ceria species are modeled as CeO2 or Ce2O4 moieties or as a small nanoparticle, Ce13O26, on the (100) and (001) surfaces of a γ-Al2O3 slab. Among the studied structures the incorporation of Ce(4+) ions in cavities of...
