  5. 4. Novel electrode and photoelectrode materials for hydrogen production based on molecular catalysts

    Författare :Andrew J. Bagnall; Leif Hammarström; Vincent Artero; Sascha Ott; Alexander Cowan; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; electrochemical mechanism; hydrogen; artificial photosynthesis; molecular catalyst; hydrogen evolution; cobalt; Kemi; Chemistry;

    Sammanfattning : The PhD project focussed on the application of a cobalt tetraazamacrocyclic complex, in the literature commonly referred to as [Co(CR)Cl2]+ as a molecular catalyst for the hydrogen evolution reaction (HER). This was within the broader scope of the EU MSCA H2020 ITN ‘eSCALED’ project, which primarily aimed to create artificial leaf devices for the storage of solar energy in chemical fuels and, as part of this, sought the development of novel bio-inspired and scalable materials.

  7. 5. Mimicking Nature – Synthesis and Characterisation of Manganese Complexes of Relevance to Artificial Photosynthesis

    Författare :Gustav Berggren; F. Magnus Anderlund; Leif Hammarström; Vincent Pecoraro; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Manganese; biomimetic; artificial photosynthesis; water splitting; homogeneous catalysis; Chemistry; Kemi; fysikalisk kemi; Physical Chemistry;

    Sammanfattning : The development of efficient catalyst for water oxidation is of paramount importance to artificial photosynthesis, but before this can be achieved a deeper understanding of this reaction is essential. In nature this reaction occurs in a tetranuclear Mn-cluster which serves as the work-horse of oxygenic photosynthesis. LÄS MER
