Multimetallic Atomically Precise and Nanoscale Models for Reactive Sites (A07*)

• Subject Area: Solid State and Surface Chemistry, Material Synthesis
• Term: since 2025
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 426888090

A07N focuses on the atomically-precise synthesis of nanostructured cluster-based model systems of the reactive site of catalysts including metals such as Ru, Rh, Pd, Pt and/or Ce and their structural and catalytic characterization in situ and ex situ, using electron and X-ray-based diffraction, spectroscopic, and imaging methods. Reactivity studies with NH3/CH4 with O2 address as-prepared clusters in the gas phase using hybrid mass spectrometry and the evolution of supported clusters using advanced transmission electron microscopy. We aim to achieve a profound understanding of structures and key processes at the atomic scale and of these species as catalysts themselves.
