  2. 1. Metal-Organic Complexes at Surfaces

    Author : Cristina Isvoranu; Synkrotronljusfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; x-ray absorption spectroscopy; x-ray photoelectron spectroscopy; bi-isonicotinic acid; oxalic acid; spin change; gas adsorption; metal-organic complex; iron phthalocyanine; scanning tunneling spectroscopy; resonant photoemission spectroscopy;

    Abstract : The adsorption of different metal-organic complexes at surfaces was investigated by spectroscopic techniques (x-ray photoemission spectroscopy, x-ray absorption spectroscopy, resonant photoemission spectroscopy) and by scanning tunnelling microscopy. The investigation methods are able to provide atomic scale information on the studied systems, which moreover originates from the top-most atomic layers in a sample, meaning that they are surface sensitive techniques.

    Abstract : Metal-organic frameworks (MOFs) are crystalline hybrid materials with interesting chemical and physical properties. This thesis is focused on the synthesis and characterization of different MOFs and their use in heterogeneous catalysis. READ MORE

  5. 3. Mimicking the Outer Coordination Sphere in [FeFe]-Hydrogenase Active Site Models : From Extended Ligand Design to Metal-Organic Frameworks

    Author : Sonja Pullen; Sascha Ott; Patrick L. Holland; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; [FeFe]-hydrogenases; outer coordination sphere; model complexes; biomimetic catalysis; artificial photosynthesis; metal-organic frameworks;

    Abstract : Biomimetic catalysis is an important research field, as a better understanding of nature´s powerful toolbox for the conversion of molecules can lead to technological progress. [FeFe]-hydrogenases are very efficient catalysts for hydrogen production. These enzymes play a crucial role in the metabolism of green algae and certain cyanobacteria. READ MORE
