1. Adsorption and reactions of sulfur dioxide on TiO2 surfaces : Fundamental studies on single crystals and nanoparticles
Sammanfattning : Titanium dioxide (TiO2) is a material that is well-known among researchers in environmental science but is perhaps less well-known by the general public. It is commonly used in white paint because of its ability to scatter visible light, and for this reason it is manufactured at a large industrial scale. LÄS MER
2. Towards Abatement of Selected Emissions from Metals Manufacturing
Sammanfattning : Although the metallurgical industry has made great strides in the reduction of unwanted emissions to the atmosphere as a result of production processes, significant challenges still exist. From a global perspective, even large reductions in emissions per produced ton become immaterial when considering that the total world production of metals continues to increase. LÄS MER
3. 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.

4. Vehicle emissions abatement: NO oxidation and ammonia SCR
Sammanfattning : The design and the development of catalytic systems for reducing vehicle emissions is a complex task due to the variety of components in a wide range of gas flow and temperature. A complete system is, therefore, composed of a series of catalysts or catalytic systems, each of which is dealing with a particular aspect of the abatement process. LÄS MER
5. Capturing Air Pollutants : Photochemical Adsorption and Degradation of SO2, NO2 and CO2 on Titanium Dioxide
Sammanfattning : Titanium dioxide (TiO2) is a material with many useful properties. It is used most widely as a pigment in white paint, although in technological research it is better known for its ability to catalyze chemical reactions during light absorption. LÄS MER
