The environment, such as temperature, gas and pressure, has a significant impact on the catalyst surfaces, which may result in structural and electronic changes during reactions. It is therefore essential to investigate the structural evolution of nanocatalysts during real reaction conditions to understand how the environment affects the catalytic nanocrystals and the catalytic mechanism at the atomic scale. In this talk, I will report our recent progress in studying the dynamic behaviors of catalytic nanocrystals under gas environment using advanced environmental TEM in low pressure and gas cell system up to atmospheric pressure. The effect of environment on the surfaces and interfaces of supported catalysts will be discussed.
