1. Surface Reactivity and Electronic Structure of Metal Oxides
Sammanfattning : The foci of this thesis are the metal oxides Cu2O, ZnO and Fe3O4 and their interaction with water and sulfur dioxide (SO2). The intention is to study SO2-induced atmospheric corrosion on a molecular level. All studies are based on photoelectron spectroscopy (PES) and scanning tunneling microscopy (STM) measurements.

2. In-situ Studies of Spontaneous Potential Oscillations during Electrochemical Deposition of Copper and Cuprous Oxide
Sammanfattning : Self-oscillating behaviour in alkaline Cu(II)-lactate and -tartrate systems has been investigated by in-situ pH and confocal Raman spectroscopy measurements. Formation of Cu(II)-lactate and -tartrate complexes is a key factor underlying the self-oscillations. LÄS MER
3. Experimental investigations of model catalytic surface reactions on metal and metal oxide surfaces
Sammanfattning : In the development of renewable energies catalysis plays an important role, for example in the production of H2 gas that drives fuel cells, or in the decomposition of annoying by-products of renewable energy production. Most catalysts and catalytic processes currently used in the industry have their roots in macroscopic empirical investigations and trial and error-based optimization. LÄS MER
4. The initial atmospheric corrosion of copper and zinc induced by carboxylic acids : Quantitative in situ analysis and computer simulations
Sammanfattning : Degradation of metals through atmospheric corrosion is a most important and costly phenomenon with significant effects on, e.g., the lifespan of industrial materials, the reliability of electronic components and military equipment, and the aesthetic appearance of our cultural heritage.

5. Experimental femtosecond-laser based investigations of model catalytic surface reactions
Sammanfattning : In order to be able to design novel catalytic processes more efficiently, detailed understanding of the catalyst-reactant interaction and the dynamics of the microscopic reaction steps is needed. The present thesis aims to contribute to the fundamental understanding of catalyst reactant systems by means of experiments using model systems in Ultra High Vacuum (UHV). LÄS MER
