1. Water oxidation : From Molecular Systems to Functional Devices
Sammanfattning : The production of hydrogen gas, through the process of water splitting,is one of the most promising concepts for the production of clean andrenewable fuel.The introduction of this thesis provides a brief overview of fossil fuelsand the need for an energy transition towards clean and renewable energy.

2. Biomimetic Reactions : Water Oxidation and Aerobic Oxidation
Sammanfattning : This thesis deals mainly with two oxidation reactions: water oxidation and aerobic oxidation, both of which have been applied in a biomimetic fashion. In the former reaction molecular oxygen is generated whereas in the latter it was used as terminal oxidant in oxidation reactions. LÄS MER
3. Nanostructured Fuel Cell Catalysts
Sammanfattning : A long term challenge for society is to develop sustainable energy systems to reduce the dependence on fossil fuels and to decrease air pollution. This requires new alternatives regarding the supply of energy and increased efficiency of the future energy systems. Fuel cell technology is one such possible alternative. LÄS MER
4. Characterization of Carbon Oxidation Kinetics for Particulate Matter Reduction Technologies
Sammanfattning : Transport related emissions of particulate matter (PM) represent a significant health risk and are therefore strictly regulated in most developed countries. An efficient technique to reduce emissions of combustion particles is to capture the particles in a filter, which must be subsequently regenerated by oxidation of the carbonaceous fraction of the PM.

5. Artificial Water Splitting: Ruthenium Complexes for Water Oxidation
Sammanfattning : This thesis concerns the development and study of Ru-based water oxidation catalysts (WOCs) which are the essential components for solar energy conversion to fuels. The first chapter gives a general introduction about the field of homogenous water oxidation catalysis, including the catalytic mechanisms and the catalytic activities of some selected WOCs as well as the concerns of catalyst design.
