Observing Chemical Dynamics: In-situ Electron Microscopy
This lecture by the instructor covers the topic of in-situ electron microscopy for observing chemical dynamics, focusing on active catalysts and dissipative structures. The lecture delves into CO oxidation on Pt, graphene CVD on various substrates, NO₂ hydrogenation on Pt, and red-ox dynamics of Ni in H₂/O₂. The instructor discusses the importance of studying catalysts in their active state and the complexity of surface reactions on metal surfaces. Various techniques such as SEM, TEM, and XAS-XRD are highlighted for their role in understanding redox reactions and metal-support interactions.
