Abstract: The past decade or so have seen a number of technological advances in the field of transmission electron microscopy that have dramatically enhanced both the utility and utilization of the instrument in the field of heterogeneous catalysis. These include aberration correction, enhanced detectors and improvements in simulation and analysis software. In this presentation, I will present several specific examples from both my own research and from others in the field to provide a general overview of the state of the art. In specific, I will describe the limits of spatial, spectroscopic and temporal energy resolution, and demonstrate how one can perform both real time and operando measurements do characterize the interrelationships between catalyst structure and catalyst function. Through the presentation, I will emphasize how these techniques are being implemented at the Singh Center for Nanotechnology at the University of Pennsylvania and how they are thus accessible to members of the Catalyst Club of Philadelphia.
