Heterogeneous gas-solid catalyst reactions occur on the
atomic scale and there is increasing evidence single atoms
and very small clusters can act as primary active sites in
chemical reactions. Aberration corrected environmental
scanning transmission electron microscope (AC ESTEM) has
been developed for novel studies of nanoparticle catalysts
with Angstrom (0.1 nm) resolution in gas. It extends high
vacuum analyses with full analytical facilities and unrestricted
high angle annular dark field (HAADF) imaging of
single atoms, small clusters and nanoparticles in dynamic
in-situ experiments with controlled gas reaction environments
at initial operating temperatures up to > 500 ◦C
