  2. 2. Water splitting by heterogeneous catalysis

    University dissertation from Stockholm : Department of Materials and Environmental Chemistry, Stockholm University

    Author : Henrik Svengren; Mats Johnsson; Tomas Edvinsson; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Faradaic efficiency; electrocatalysis; electrolysis; water oxidation; hydrogen reduction; H2; O2; mass spectrometry; oorganisk kemi; Inorganic Chemistry;

    Abstract : A sustainable solution for meeting the energy demands at our planet is by utilizing wind-, solar-, wave-, thermal-, biomass- and hydroelectric power. These renewable and CO2 emission-free energy sources are highly variable in terms of spatial and temporal availability over the Earth, introducing the need for an appropriate method of storing and carrying energy.

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

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Lele Duan; Licheng Sun; Matthias Beller; [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. Water splitting in natural and artificial photosynthetic systems

    University dissertation from Umeå : Umeå University

    Author : Sergey Koroidov; Johannes Messinger; Richard J. Debus; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Water splitting; photosystem II; artificial catalyst; MIMS; inorganic carbon;

    Abstract : Photosynthesis is the unique biological process that converts carbon dioxide into organic compounds, for example sugars, using the energy of sunlight. Thereby solar energy is converted into chemical energy. Nearly all life depends on this reaction, either directly, or indirectly as the ultimate source of their food. READ MORE

  5. 5. Photosynthetic water oxidation the function of two extrinsic proteins

    University dissertation from Umeå : Fysiologisk botanik

    Author : Tatiana Shutova; Göran Samuelsson; Stenbjörn Styring; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; photosystem II; Psb0; Cah3; water oxidation; NATURAL SCIENCES Biology Organism biology Plant physiology; NATURVETENSKAP Biologi Organismbiologi Växtfysiologi;

    Abstract : The solar energy accumulated by photosynthesis over billions of years is the sole source of energy available on Earth. Photosystem II (PSII) uses the sunlight to split water, an energetically unfavorable reaction where electrons and protons are extracted from water and oxygen is released as a by-product. READ MORE
