Spectroscopy and Kinetics on Metal Cluster Surfaces: The Fe/N2, Co/N2 and Ni/N2 systems — •Sebastian Dillinger, Jennifer Mohrbach, Annika Steiner, and Gereon Niedner-Schatteburg — Fachbereich Chemie and Forschungszentrum OPTIMAS, Technische Universität Kaiserslautern, 67663 Kaiserslautern, Germany
We present kinetic data of N2 adsorption on isolated cationic Fe/Co/Ni clusters in combination with Infrared (Multi) Photon Dissociation (IR(M)PD) spectra of the cluster adsorbate complexes at cryo temperatures. We will display and discuss the cluster size range of n=7-20. We find metal, cluster size and adsorbate number dependent effects in the IR(M)PD spectra as well as in the kinetic data: Trends and exceptions superpose. For our experiments we utilized a unique tandem cryo trap setup at 12 K to 26 K.
