  2. 1. Modeling Photofunctional Transition Metal Complexes

    Author : Iria Bolano Losada; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; density functional theory; earth-abundant; molecular dynamics; quantum chemistry; photosensitizer; photophysics; photochemistry; solar fuels; solar energy conversion; transition metal complexes;

    Abstract : Transition metal complexes play a crucial role in solar energy conversion. These coordination compounds have promising applications in dye-sensitized solar cells and photocatalysis, with particular interest in solar fuel production. READ MORE

  4. 2. Structural, Electronic and Reactive Properties of Pentapyridyl - Base Metal Complexes : Relevance for Water Oxidation Catalysis

    Author : Manuel Boniolo; Johannes Messinger; Antoni Llobet; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Water oxidation; Base metal complexes; Redox potential; Spin crossover; Magnetic anisotropy; Chemistry with specialization in Molecular Biomimetics; Kemi med inriktning mot molekylär biomimetik;

    Abstract : The rationalization of chemical-physical proprieties of transition metal complexes is fundamental in order to understand and tune their reactivity. In this thesis, a systematic investigation of the geometrical and electronic properties of [M(Py5OH)Cl]+ complexes (M= Mn, Fe, Co, Ni) has been performed, and their ability to act as molecular water oxidation catalysts has been probed.

  5. 3. Photocatalysis beyond conventional precious metal complexes

    Author : Rickard Lindroth; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Heterogenization; Iron photocatalysis;

    Abstract : Precious metals, e.g. Ru and Ir, are expensive, scarce and non-renewable resources. As oppose to many renewable resources, these cannot be deliberately produced wherever one wishes. READ MORE

  6. 4. Electronic structure investigations of transition metal complexes through X-ray spectroscopy

    Author : Meiyuan Guo; Marcus Lundberg; Hélène Bolvin; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; transition metal complexes; x-ray spectroscopy; electronic structures; Kemi; Chemistry;

    Abstract : Catalysts based on the first-row (3d) transition metals are commonly seen in chemical and biological reactions. To understand the role of the transition metal in the catalyst, the element specific technique core level spectroscopy is used to probe the electronic structure and geometric properties centered around the metal site.

  7. 5. Development of metal complexes for water oxidation

    Author : Bao-Lin Lee; Sascha Tiede; Stockholms universitet; []
    Keywords : ;

    Abstract : In the course of developing a water oxidation catalyst, five metal complexes have been synthesised, characterised and studied for catalytic activity. Three of them are dinuclear complexes (Ru, Co and Cu) of 2,6-bis[(2-hydroxybenzyl)-(2-pyridylmethyl)aminomethyl]-4-methylphenol (H3bbpmp). READ MORE
