Infrared Spectroscopy and Quantum Chemical Calculations on Oxide-Supported Metal Parti-cles/Clusters (A04)

• Subject Area: Physical Chemistry of Solids and Surfaces, Material Characterisation ; Theoretical Chemistry: Molecules, Materials, Surfaces
• Term: since 2021
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 426888090

The goal of this project is a fundamental understanding of the active site of nanostructured metal/oxide catalysts based on a thorough surface science study combining experiment and theory on monocrystal model systems. We will focus on the spectroscopic characterization (polarization-dependent IRRAS and IR transmission in conjunction with XPS and NEXAFS) of oxide-supported Pt, Pd and PtPd nanoparticles under activation and reaction conditions. Structural information about the metal clusters in gas phase and deposited on TiO2, CeO2, and Al2O3 surfaces will be determined by a combined quantum chemical and experimental approach.
