“…While a strong development toward environmental TEM has occurred since the 70s, , detection capabilities did not allow routine atomic resolution under controlled atmosphere. With the advent of aberration-correction and high speed cameras in the past decade, HRTEM imaging has become a key technique to allow atomic-scale analysis in real time in environmental conditions. − …”

Ceria is one of the world's most prominent material for applications in heterogeneous catalysis, as catalyst support or catalyst itself. Despite an exhaustive literature on the structure of reactive facets of CeO in line with its catalytic mechanisms, the temporal evolution of the atomic surface structure exposed to realistic redox conditions remains elusive. Here, we provide a direct visualization of the atomic mobility of cerium atoms on {100} surfaces of CeO nanocubes at room temperature in high vacuum, O, and CO atmospheres in an environmental transmission electron microscope. Through quantification of the cationic mobility, we demonstrate the control of the surface dynamics under exposure to O and CO atmospheres, providing opportunities for a better understanding of the intimate catalytic mechanisms.

“…Also, EELS capabilities in ETEM [28,29,64] have indicated the potential to detect catalytic activity during in situ studies [22] To achieve highest S/TEM performance when studying materials behaviour in liquid environments, graphene cells have already shown their great potential (see study of nanocrystal coalescence in Fig. 16) [117,161,175].…”
