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

    Author : Davide Ragazzon; Anders Sandell; Anne Borg; Jason F. Weaver; Uppsala universitet; []
    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

  4. 2. Theoretical Studies on the Molecular Mechanisms of Photo-Catalytic Reactions on TiO2 Surfaces

    Author : Yongfei Ji; Yi Luo; Annabella Selloni; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TiO2; First-principles; photocatalysis; Kemi; Chemistry;

    Abstract : Photocatalysis is a promising technology that can effectively convert the solar energyinto sustainable green energy. However, theoretical studies on the molecular mechanisms of photocatalytic reactions are rare. READ MORE

    Author : Andreas Mattsson; Lars Österlund; Gunnar Niklasson; Claes-Göran Granqvist; Håkan Rensmo; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : TiO2 based photocatalysis is an emerging green nanotechnology that can be used forremoval of pollutants from water and air. It has had an increased research interest, bothfrom an application and fundamental point of view, during the last decades. READ MORE

  6. 4. Adsorption and reactions of sulfur dioxide on TiO2 surfaces : Fundamental studies on single crystals and nanoparticles

    Author : David Langhammer; Lars Österlund; Anders Sandell; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Titanium dioxide (TiO2) is a material that is well-known among researchers in environmental science but is perhaps less well-known by the general public. It is commonly used in white paint because of its ability to scatter visible light, and for this reason it is manufactured at a large industrial scale. READ MORE

  7. 5. Infrared spectroscopy studies of adsorption and photochemistry on TiO2 surfaces : From single crystals to nanostructured materials

    Author : Andreas Mattsson; Lars Österlund; Per-Anders Carlsson; Uppsala universitet; []
