Overview:

Catalysts are increasingly indispensable to industrial processes used for producing essential chemicals and fuels. Heterogeneous catalysts, e.g. solid catalysts that promote reactions among gaseous reactants, are important for refining conventional fossil fuels, for redox functionality in fuel cell or pollution control applications, etc. To improve the activity, selectivity and stability of nanocatalysts, researchers need to understand at the atomic scale the relationship between catalyst/support structure and its function.

In this webinar, we will present the environmental transmission electron microscope (ETEM) that allows researchers to directly observe catalytic materials at atomic-scale. Utilizing ETEM, scientists are able to visualize structural morphology of the catalyst in (near) operational gaseous environments. We will present current research that demonstrates ETEM's increasing role in catalysis studies.

Key Learning Objectives:

• The importance of visualizing catalysts under (near) reactive conditions

• How ETEM has been applied in catalysis research

• The unique ability of aberration corrected ETEM to visualize nanocatalysts in situ at the atomic scale
