Characterization of Catalyst Materials in the Electron and Atom Probe Microscopes


EMSL Project ID
46700

Abstract

The aim of this proposal is to combine existing techniques in the electron and atom-probe microscopes to afford novel methods for a fundamental understanding of catalyst interactions with atomic resolution and chemical sensitivity. Key scientific ideas underlying the proposal are (a) the capability to precisely modify (and properly characterize) the reactive sites, (b) a selection of test reactions to characterize catalyst performance, and (c) the application of techniques that allow fundamental understanding of how the catalysts function and enable predicting the behavior of new types of catalysts. Together with external collaborators, this proposal will aim to synthesize metal clusters and their supports, characterize them at various stages of preparation and under various conditions (including catalytic reaction conditions), determine their structures and reactivities, and determine how their catalytic properties depend on their compositions and structures.
