Nanomachines & Nanomanipulation Characterization of catalysts based on supported metallic clusters or individual atoms

This project aims at the characterization novel structures for catalysis based on metallic clusters, typically 1-2 nm Pt and Rh nanocrystals, supported on complex mesoporous structures. The main goal is to detect these atomic clusters and to evaluate their exposed sites and the interface with the support. Typical microscopy approaches used in such projects are aberration-corrected HRSTEM, HAADF signal processing, XEDS spectroscopy and atomic scale modeling. 

The motivation for the studies within this project is to support the performance improvement of many applications that depend on efficient catalysts, water splitting for H2 generation for example, by understanding the materials’ morphology at the atomic scale. This project represents a collaboration with Leibniz-Institut für Katalyse (Germany).
