In this work, we investigate the adsorption of carbon dioxide on rhodium (Rh) nanocrystals
as well as its catalytic reaction with hydrogen, at the nanoscale, using field ion microscopy
(FIM), video-field emission microscopy (FEM), and one-dimensional atom probe (1DAP). A
FEM pattern-and-brightness analysis during the ongoing dissociation process at 700 K
provides information on various facet reactivities and how these facets communicate with
each other. Our results show CO2 dissociative adsorption to be fastest on {012} facets …
