Abstract:
The environment,such as temperature, gas and pressure, has a significant impact on the catalystsurfaces, which may result in structural and electronic changes including gasadsorption, electron transfer and stress variation, making it challenging toaccurately interpret the physical and chemical properties of nanocrystalcatalysts. To address such an important issue, we introduce the environmentinto transmission electron microscope, which is supposed to work in highvacuum, to study the structural evolution and its impact on the physicochemicalproperties of nanocatalysts at the atomic scale under gas environment. In thistalk, I will present our recent in-situ studies on nanocrystal catalysts underhigh temperature and/or gas environment (up to 105Pa using gas-cellsystem) in TEM. The effect of the environment on nanocrystal catalysts will bediscussed.
