  4. 18. Outer Coordination Spheres Engineering of Ru-based Molecular Water Oxidation Catalysts

    Författare :Tianqi Liu; Licheng Sun; Julio Lloret-Fillol; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; solar fuels; water oxidation; catalysis; ruthenium complex; Ru-bda; Ru-pda; outer coordination sphere; hydrophobic interactions; Kemi; Chemistry;

    Sammanfattning : The outer coordination sphere plays a vital role in metalloenzyme catalysis, while this principle is relatively less considered in the design of man-made molecular catalysts. This thesis investigates the role of outer coordination spheres in water oxidation by a series of ruthenium-based complexes. LÄS MER

  5. 19. Heterometallic Oxo-Alkoxides of Europium, Titanium and Potassium

    Författare :Erik Berger; Gunnar Westin; Lars Eriksson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Alkoxides; Europium; Lanthanoids; Electronic absorption spectroscopy; f-f spectroscopy; Coordination chemistry; Koordinationskemi; Inorganic Chemistry; Oorganisk kemi;

    Sammanfattning : Coordination compounds of europium and titanium with oxide, ethoxide (OCH2CH3), iso-propoxide (OCH(CH3)2) and tert-butoxide (OC(CH3)3) ligands have been studied. These belong to the general class of oxo-alkoxides, MxOy(OR)z, with alkoxide ligands (OR) containing an organic, aliphatic part R. LÄS MER

  7. 20. Transition Metal Hydrides : Biomimetic Studies and Catalytic Applications
