  2. 1. Photophysics and Photochemistry of Iron Carbene Complexes

    Author : Linnea Lindh; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; tidsupplöst spektroskopi; täthetsfunktionalteori; järn-komplex; färgämne; grätzelsolcell; fotokatalys; elektronöverföringsreaktion; time-resolved spectroscopy; density functional theory; earth-abundant; iron-complex; photosensitiser; dye-sensitised solar cell; photocatalysis; electron transfer;

    Abstract : Nature captures sunlight via light-absorbing molecules.Similarly, photosensitisers are used in applications of solar cells and artificial photosynthesis to absorb sunlight, and transfer the excited electron. READ MORE

  4. 2. 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

  5. 3. Stepping into Catalysis : Kinetic and Mechanistic Investigations of Photo- and Electrocatalytic Hydrogen Production with Natural and Synthetic Molecular Catalysts

    Author : Daniel Streich; Leif Hammarström; Reiner Lomoth; Clifford Kubiak; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Artificial photosynthesis; photocatalysis; electrocatalysis; hydrogen production; proton reduction; hydrogenase; iron complex; active site model; catalytic mechanism; transient absorption; spectroscopy; electrochemistry; cyclic voltammetry; Kemi med inriktning mot kemisk fysik; Chemistry with specialization in Chemical Physics;

    Abstract : In light of its rapidly growing energy demand, human society has an urgent need to become much more strongly reliant on renewable and sustainable energy carriers. Molecular hydrogen made from water with solar energy could provide an ideal case. READ MORE

  6. 4. Solution-Chemical Synthesis of Cobalt and Iron:Zinc Oxide Nanocomposite Films

    Author : Ulrika Lagerqvist; Annika Pohl; Peter Svedlindh; Mikael Ottosson; Theodor Schneller; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fe:Zn oxide; Co-CoO; Solution-chemical synthesis; Heat treatment parameters; Nanocomposite; Film; Multilayer; Phase ratio; Phase distribution; Exchange bias; Magnetism; Photocatalysis; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

    Abstract : The potentially most important challenges today are related to energy and the environment. New materials and methods are needed in order to, in a sustainable way, convert and store energy, reduce pollution, and clean the air and water from contaminations. READ MORE

  7. 5. New Catalytic Systems for Light-driven Hydrogen Evolution

    Author : Chuanshuai Li; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; photocatalysis; hydrogen evolution; semiconductor; molecular catalyst; charge transfer; mechanism;

    Abstract : Solar-driven reduction of water to produce hydrogen is one of the most promising ways to develop sustainable cleanenergy for the future. The challenge in photocatalytic hydrogen evolution research is to design inexpensive catalystsand construct efficient hydrogen production systems. READ MORE
