Structure and Chemical Reactivity of Size-Selected Clusters in Gas Phase (A01)

• Subject Area: Physical Chemistry of Molecules, Liquids and Interfaces, Biophysical Chemistry
• Term: since 2021
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 426888090

Project A1 aims to unravel the influence of size, structure, charge and oxidation state on the oxidation kinetics of CO, NO and CH4 adsorbates on ionic Ptn and Pdn (n<100) clusters and their alloys over a large temperature and partial pressure range. To this end we will use a unique combination of structure sensitive methods (TIED, IRPD) and reactivity measurements (RITMS) in gas-phase. Together with ab initio computations these experiments will help to infer the intrinsic structural and electronic origins for catalytic activity. These insights will allow disentangling support effects from intrinsic properties and can help to control and tune the cluster support interaction for a given reaction.
