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...
Atomic‐scale analysis of the cation valence state distribution will help to understand intrinsic features of oxygen vacancies (VO) inside metal oxide nanocrystals, which, however, remains a great challenge. In this work, the distribution of cerium valence states across the ultrafine CeO2 nanocubes (NCs) perpendicular to the {100} exposed facet is investigated layer‐by‐layer using state‐of‐the‐art...
