Cerium Valence State Distribution: Atomic-Scale Valence State Distribution inside Ultrafine CeO2 Nanocubes and Its Size Dependence (Small 42/2018)
Graphical Abstract
In article number 1802915, Tadafumi Adschiri, Yuichi Ikuhara, and co-workers report the atomic-scale analysis of the distribution of cerium valence states in surfactant-modified CeO2 nanocubes using scanning transmission electron microscopy and electron energy loss spectroscopy. A nanosized effect induces local lattice expansion, which results in the increasing amount of Ce3+ cations in the central layer of the ultrafine CeO2 nanocubes.
