O 3: Focus Session: Single Atom Catalysis 1

Montag, 5. September 2022, 10:30–12:45, H4

The field of single atom catalysis has emerged rapidly in recent years out of the desire to utilize less and less precious metals, and remarkable successes have been reported in thermo-, electro-, and photo-catalysis. While much of the early focus was on establishing synthesis routes to achieve atomic dispersion, it has become clear that "single atom" systems cannot be considered as the smallest possible nanoparticle. Because isolated adatoms are stabilized by chemical bonds to the support, they have much more in common with mononuclear complexes used in homogenous catalysis. Thus, the focus has now changed towards understanding the role of coordination of the active site, and developing ways to tailor it toward specific processes. This has led to much interest in fundamental work, which opens up a tremendous opportunity for surface science to contribute to a hot topic in catalysis.
