Multiscale characterizations of structural evolution in mesoporous CeO2

Abstract

In situ ultra-small-angle and wide-angle X-ray scattering enables simultaneous tracking of the structural parameters of mesoporous CeO₂ from the atomic scale to the micron-size scale. This multiscale approach provides a path to better understand structure–property relationships in mesoporous polycrystalline materials under dynamic conditions such as high temperature cycling.
