Title: Electron microscopy insights into transformations of electrocatalysts during operation

Abstract: The field of in-situ electron microscopy for probing the evolution of nanomaterials during electrochemical processes in liquids has quickly developed in recent years due to the advancements in specialized apparatuses. The technique enables observations of dynamic changes associated with morphological, microstructural, and chemical evolution of surfaces and interfaces when exposed to appropriate stimuli and has the potential to enhance our mechanistic understanding of the processes that take place during device operation.

During this talk, Prof. Tileli will discuss the development and application of in-situ nanoanalytical transmission electron microscopy techniques on two distinctive electrocatalytic processes; cycling of Co-based oxides for oxygen evolution reaction, and monitoring dissolution/redeposition of Cu nanocatalysts during CO2 electroreduction, as well as the challenges involved with performing such experiments.
