A6 – Probing dynamics of supported Pt and Pd catalysts through scale bridging analytical in situ scanning and transmission electron microscopy

Objective

The aim of project A6 is to investigate dynamic processes of individual and collective nanoparticle/substrate interactions as a function of synthesis and process conditions, temperature and chemical environment. Complementary to the other electron microscopy projects in the CRC1441, project A6 combines the analytical in situ environmental scanning electron microscopy with transmission electron microscopy and thus expands the scale bridging approach by closing the gap between the nano- and mesoscale. This new methodological concept thus inter-links the collaborative efforts of projects A3, A5, B1 and B3 with those of C3 across different length scales.
