  2. 1. Potential Electrocatalysts for Water Splitting Devices : A Journey Through the Opportunities and Challenges of Catalyst Classes

    Author : Robin N. Dürr; Leif Hammarström; Bruno Jousselme; Tomas Edvinsson; Haining Tian; Kevin Sivula; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electrocatalysis; Electrolyzer cell; HER catalyst; OER catalyst; Water splitting; Kemi; Chemistry;

    Abstract : In this thesis work, different classes of catalysts and their suitability for integration into an electrolyzer cell has been investigated.Ruthenium based molecular catalysts have shown high activities and stabilities towards water oxidation in neutral pH. Especially the oligomeric catalysts exhibited a superior performance. READ MORE

  4. 2. 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.

    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
