In situ three-dimensional imaging of strain in gold nanocrystals during catalytic oxidation
Nanoscale advances, 2019•pubs.rsc.org
The chemical properties of materials are dependent on dynamic changes in their three-
dimensional (3D) structure as well as on the reactive environment. We report an in situ 3D
imaging study of defect dynamics of a single gold nanocrystal. Our findings offer an insight
into its dynamic nanostructure and unravel the formation of a nanotwin network under CO
oxidation conditions. In situ/operando defect dynamics imaging paves the way to elucidate
chemical processes at the single nano-object level towards defect-engineered …
