Laserspectroscopy on surface reaction products

Project: Research project

Project Details


Chemical reactions based on heterogeneous catalysis play an important role in modern technology. The understanding of the basic steps in catalysis like adsorption, surface diffusion, recombination and desorption is the key to produce new catalysts. In this project the basic steps of the desorption of simple molecules like H2 or D2 from single crystal metal surfaces are investigated. In particular the vibrational and rotational state distribution of the desorbing molecules is investigated with the help of laser spectroscopy (REMPI: resonantly enhanced multi-photon ionization. From the experimental results one gets information on the type of reaction, e.g. Eley-Rideal or Langmuir Hinshelwood.
