  2. 2. Biomimetic Reactions Water Oxidation and Aerobic Oxidation

    University dissertation from Stockholm : Department of Organic Chemistry, Stockholm University

    Author : Lien-Hoa Tran; Stockholms universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cobalt II salophen; oxygen-activating catalyst; hybrid; manganese complex; epoxidation; water oxidation.; NATURAL SCIENCES Chemistry Organic chemistry; NATURVETENSKAP Kemi 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

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

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Lele Duan; KTH.; [2011]
    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.

  4. 4. Ru-Based Water Oxidation Catalysts Development and Mechanistic Studies

    University dissertation from Stockholm : Department of Organic Chemistry, Stockholm University

    Author : Andrey Shatskiy; Stockholms universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ruthenium; catalysis; water oxidation; artificial photosynthesis; Organic Chemistry; organisk kemi;

    Abstract : 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. READ MORE

  5. 5. Mononuclear Ruthenium Complexes that Catalyze Water to Dioxgen Oxidation
