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

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

    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

  4. 3. Artificial Water Splitting: Ruthenium Complexes for Water Oxidation

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

    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.

  7. 5. Ru-Based Water Oxidation Catalysts : Development and Mechanistic Studies

    Författare :Andrey Shatskiy; Björn Åkermark; Martin Albrecht; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ruthenium; catalysis; water oxidation; artificial photosynthesis; organisk kemi; Organic Chemistry;

    Sammanfattning : Oxidation of water constitutes one of the most challenging processes in artificial photosynthesis, which aims at storing solar energy in the form of chemical bonds of high-energy fuels. To facilitate this process, efficient and durable water oxidation catalysts have to be developed and integrated into the complete photosynthetic cells. LÄS MER
