  4. 2. Biomimetic Reactions : Water Oxidation and Aerobic Oxidation

    Author : Lien-Hoa Tran; Björn Åkermark; Nina Kann; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cobalt II salophen; oxygen-activating catalyst; hybrid; manganese complex; epoxidation; water oxidation.; Organic chemistry; Organisk kemi; organisk kemi; Organic Chemistry;

    Abstract : 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. READ MORE

  5. 3. Nanostructured Fuel Cell Catalysts

    Author : Marie Gustavsson; Chalmers tekniska högskola; []
    Keywords : Nafion; thin film evaporation; model catalyst; electrocatalyst; acetic acid oxidation; oxygen reduction; colloidal lithography; PEMFC; screening; Pt; formaldehyde oxidation; methanol oxidation; nanofabrication; CO oxidation; polymer electrolyte; TiOx;

    Abstract : 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. READ MORE

  6. 4. Characterization of Carbon Oxidation Kinetics for Particulate Matter Reduction Technologies

    Author : Carolin Ohlson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heterogeneous catalysis; Carbon – catalyst interaction; Soot oxidation; Particulate filter; Carbon oxidation; Global kinetics; Regeneration; Particulate matter oxidation; DPF;

    Abstract : 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.

  7. 5. Artificial Water Splitting: Ruthenium Complexes for Water Oxidation

    Author : Lele Duan; Licheng Sun; Matthias Beller; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; water oxidation; ruthenium; electrochemistry; DFT calculation; photoelectrochemistry; negatively charged ligand; catalyst;

    Abstract : 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.
