Abstract

Advances in atomic-resolution environmental transmission electron microscopy (ETEM) and related techniques for probing gas–solid reactions in situ are described. The capabilities of ETEM allow the dynamic nanostructure of heterogeneous catalysts in their functioning states to be directly monitored in real time. Applications of ETEM in catalysis are outlined, and they illustrate significant new insights into the dynamic nanostructure of the catalyst materials and their modes of operation.
