  2. 1. Adsorption of molecular thin films on metal and metal oxide surfaces

    Author : Zahra Besharat; Mats Göthelid; Mark Rutland; Magnus Johnson; W. Gregory Sawyer; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Self assembled monolayer SAM ; dye synthesis solar cell DSSC ; thiol; selenol; Cu2O 100 ; Cu2O 111 and dehydrogenation; Fysik; Physics; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : Metal and metal oxides are widely used in industry, and to optimize their performance their surfaces are commonly functionalized by the formation of thin films. Self-assembled monolayers (SAMs) are deposited on metals or metal oxides either from solution or by gas deposition. READ MORE

  4. 2. Surface Reactivity and Electronic Structure of Metal Oxides

    Author : Anneli Önsten; Ulf Karlsson; Anne Borg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oxides; surfaces; defects; cuprous oxide; zinc oxide; magnetite; water; OH; sulfur dioxide; photoelectron spectroscopy; scanning tunneling microscopy; Material physics with surface physics; Materialfysik med ytfysik;

    Abstract : The foci of this thesis are the metal oxides Cu2O, ZnO and Fe3O4 and their interaction with water and sulfur dioxide (SO2). The intention is to study SO2-induced atmospheric corrosion on a molecular level. All studies are based on photoelectron spectroscopy (PES) and scanning tunneling microscopy (STM) measurements.

  5. 3. Transition metal oxide surfaces : Surface structures and molecular interaction

    Author : Markus Soldemo; Jonas Weissenrieder; Mats Göthelid; Sarp Kaya; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Abstract : Metal oxides are both corrosion products and useful materials with a wide range of applications. Two of the most used metals today are iron and copper. In this thesis, surface structures and molecular interaction with surfaces of iron oxides and copper oxides are studied using spectroscopy and microscopy methods. READ MORE

  6. 4. Experimental femtosecond-laser based investigations of model catalytic surface reactions

    Author : Kess Marks; Henrik Öström; Stefano Bonetti; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; kemisk fysik; Chemical Physics;

    Abstract : In order to be able to design novel catalytic processes more efficiently, detailed understanding of the catalyst-reactant interaction and the dynamics of the microscopic reaction steps is needed. The present thesis aims to contribute to the fundamental understanding of catalyst reactant systems by means of experiments using model systems in Ultra High Vacuum (UHV). READ MORE

  7. 5. Dissociative Adsorption of CO2 on Copper: The Role of Steps

    Author : Benjamin Hagman; Synkrotronljusfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; koppar; CO2; Copper surface; Carbon Dioxide : chemistry; Dissociative adsorption; Surface oxidation; Ambient pressure X-ray photoelectron spectroscopy APXPS ; Surface X-ray diffraction SXRD ;

    Abstract : CO2 chemistry has received significant interest in recent time, due to the greenhouse effects of CO2 emissions and the resulting climate change. CO2 reduction reactions, such as methanol synthesis and reverse water-gas shift, is providing a route for recycling of CO2 and thus limiting the CO2 emissions. READ MORE
