2. 1. Synthetic [FeFe] Hydrogenase Active Site Model Complexes

   Author : Lennart Schwartz; Sascha Ott; Marcetta Y. Darensbourg; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; hydrogenase mimic; proton reduction; bioinorganic chemistry; diiron hexacarbonyl complexes; artifical photosynthesis; hydrogen; Organic chemistry; Organisk kemi;

   Abstract : [FeFe]-Hydrogenases (H2ases) are metalloenzymes that can catalyze the reversible reduction of protons to molecular hydrogen as part of the metabolism of certain cyanobacteria and green algae. Due to the low availability of the enzyme, synthetic complexes that mimic the natural active site in structure, function and activity are highly sought after. READ MORE

4. 2. Molecular Approaches to Photochemical Solar Energy Conversion : Towards Synthetic Catalysts for Water Oxidation and Proton Reduction

   Author : Gerriet Eilers; Reiner Lomoth; Leif Hammarström; Wolfgang Lubitz; Uppsala universitet; []
   Keywords : Physical chemistry; artificial photosynthesis; solar fuel; WOC; OEC; accumulative electron transfer; hydrogenase mimic; oxygen evolution; proton reduction; water oxidation; Fysikalisk kemi;

   Abstract : A molecular system capable of photoinduced water splitting is an attractive approach to solar energy conversion. This thesis deals with the functional characterization of molecular building blocks for the three principal functions of such a molecular system: Photoinduced accumulative charge separation, catalytic water oxidation, and catalytic proton reduction.

5. 3. Studies of second coordination sphere effects and metal variations on [FeFe]-hydrogenase mimics

   Author : Holly J. Redman; Gustav Berggren; Pickett Chris; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; hydrogenases; synthesis; inorganic chemistry; molecular biomimetics; spectroscopy; FTIR; cyclic voltammetry; catalysis; Chemistry with specialization in Molecular Biomimetics; Kemi med inriktning mot molekylär biomimetik;

   Abstract : Mitigation of climate change motivates researchers to explore hydrogen as a potential energy carrier. Unfortunately, widespread use of hydrogen as an energy carrier is limited by numerous challenges in its production, including high energy consumption; high economic cost; current reliance on rare metals such as platinum.

6. 4. Transition Metal Hydrides : Biomimetic Studies and Catalytic Applications

   Author : Jesper Ekström; Hans Adolfsson; Jonathan Williams; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; transition metals; catalysis; bioinorganic chemistry; hydrides; Organic chemistry; Organisk kemi; Organic Chemistry; organisk kemi;

   Abstract : In this thesis, studies of the nature of different transition metal-hydride complexes are described. The first part deals with the enantioswitchable behaviour of rhodium complexes derived from amino acids, applied in asymmetric transfer hydrogenation of ketones. READ MORE
