A07N – Multimetallic Atomically Precise and Nanoscale Models for Reactive Sites
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.
The project is funded since 2025, the second funding phase of TrackAct.
