  1. 1. Water splitting in natural and artificial photosynthetic systems

    Författare :Sergey Koroidov; Johannes Messinger; Richard J. Debus; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Water splitting; photosystem II; artificial catalyst; MIMS; inorganic carbon;

    Sammanfattning : 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. LÄS MER

  3. 2. Going for gold : A spectroelectrochemical and catalytic study of gold materials

    Författare :Sara Boscolo Bibi; Hansson Tony; Sergey Koroidov; Henrik Öström; Richard Kramer Campen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Gold oxidation; oxide-derived metals; electrochemistry; X-ray spectroscopy; optical nonlinear spectroscopy; AuNPs supported in metal oxides; mass spectrometry; kemisk fysik; Chemical Physics;

    Sammanfattning : With the increase in demand for renewable energy, understanding chemical processes is essential for improving the design of catalysts in order to achieve better performance. This thesis summarises the experimental investigation of three types of catalytic gold materials: gold oxide formed from gold films, oxide-derived gold (OD-Au) produced from gold films, and gold nanoparticles supported on metal oxides.
