  1. 1. Heterogeneous TiO2 Photocatalysis : Fundamental Chemical Aspects and Effects of Solid Phase Alterations

    Author : Veronica Diesen; Mats Jonsson; Hynd Remita; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Heterogeneous photocatalysis on TiO2 is an emerging green technology for water disinfection. The rationale for this technology is based on in-situ generation of highly reactive transitory species for degradation of organic and inorganic pollutants as well as microorganisms. READ MORE

  2. 2. Water film-mediated mineralogical transformations and photocatalytic reactions

    Author : N. Tan Luong; Jean-Francois Boily; Michael Holmboe; Alejandro Fernandez-Martinez; Umeå universitet; []

    Abstract : This thesis focuses on the application of nanocrystalline transition metal oxide TiO2, WO3 and NiO thin films in new “green” building technologies. Specifically, their physicochemical properties in photocatalytic, self-cleaning and gas sensing applications are studied. READ MORE

  4. 4. Fabrication and Characterization of Composite TiO2/Carbon Nanofilms with Enhanced Photocatalytic Activity

    Author : Raja Sellappan; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TiO2; carbon; photoluminescence; photodegradation; recombination.; Photocatalysis;

    Abstract : The work presented in this thesis is dedicated to fabrication and characterization of an efficient thin film photocatalyst for environmental cleaning and solar fuel applications. Because of its simplicity and reproducible fabrication, the chosen combination of nanometer thin titania and carbon films serves also as a model system for a wider class of photoactive materials.
