  2. 2. Titania Nanoscale Films and Surfaces Surface Science Investigation of Structure and Properties

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Davide Ragazzon; Anders Sandell; Anne Borg; Jason F. Weaver; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Photoelectron spectroscopy; PES; XPS; scanning tunneling microscopy; STM; titania; titanium oxide; TiO2; Au 111 ; gold; water; H2O; rutile;

    Abstract : This thesis presents surface science studies, investigating several aspects of titanium dioxide at the atomic scale. The greater part of this work is devoted to the preparation by chemical vapor deposition (CVD) of titanium(IV) tetraisopropoxide (TTIP) of ultrathin TiO2 or TiOx films on Au(111). READ MORE

  3. 3. Probing Atomic Scale Structure and Catalytic Properties of Cobalt Oxide Model Catalysts

    University dissertation from Lund University, Faculty of Science, Department of Physics, Division of Synchrotron Radiation Research

    Author : Alif Arman; [2016-12]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; catalysis; model systems; Co3O4 111 ; Co3O4 100 ; CoO 111 ; X-ray photoelectron spectroscopy; Scanning tunneling microscopy; Fysicumarkivet A:2017:Arman;

    Abstract : Cobalt oxides are known to be active catalysts for a number of chemical reactions, but very little is known about the atomic scale processesresponsible for the activity. The research presented in this thesis is focused on obtaining an atomic scale understanding of the chemistry of wellcharacterizedcobalt oxide model catalyst surfaces consisting of pristine and defective CoO and Co3O4 thin films with the (111) and (100)terminations supported by Ag(100), Ir(100), and Au(111) single crystal surfaces.
