  2. 1. Synthesis and Characterization of Some Nanostructured Materials for Visible Light-driven Photo Processes

    Author : Rania Elhadi Adam; Omer Nour; Magnus Willander; Nicolas Martin; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ZnO; Nanoparticles; Nanocomposites; Heterostructures; Photocatalysis;

    Abstract : Nanostructured materials for visible light driven photo-processes such as photodegradation of organic pollutants and photoelectrochemical (PEC) water oxidation for hydrogen production are very attractive because of the positive impact on the environment. Metal oxides-based nanostructures are widely used in these photoprocesses due to their unique properties. READ MORE

  4. 2. Graphene-based nanocomposites for electronics and photocatalysis

    Author : Ebrahim Chalangar; Håkan Pettersson; Magnus Willander; Omer Nour; Maria Messing; Högskolan i Halmstad; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Graphene; Zinc oxide; Silver iodine; Plasmonics; Nanocomposites; Conjugated electronics; Photocatalysis; Photodegradation;

    Abstract : The development of future electronics depends on the availability of suitable functional materials. Printed electronics, for example, relies on access to highly conductive, inexpensive and printable materials, while strong light absorption and low carrier recombination rates are demanded in photocatalysis industry.

  5. 3. 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

  6. 4. Photocatalysis beyond conventional precious metal complexes

    Author : Rickard Lindroth; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Heterogenization; Iron photocatalysis;

    Abstract : Precious metals, e.g. Ru and Ir, are expensive, scarce and non-renewable resources. As oppose to many renewable resources, these cannot be deliberately produced wherever one wishes. READ MORE

  7. 5. Low dimensional Zinc- and Copper Oxides and their Electronic, Vibrational and Photocatalytic Properties

    Author : Jakob Thyr; Tomas Edvinsson; Thomas Wågberg; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ZnO; Cu2O; CuO; Cu4O3; Photocatalysis; Raman spectroscopy; Nano materials; Quantum confinement; Quantum dots; Size dependent properties; Crystal orientation; Density functional theory; Engineering Science with specialization in Solid State Physics; Teknisk fysik med inriktning mot fasta tillståndets fysik;

    Abstract : Pollution of water resources is a growing problem in the world and this has drawn the attention to photocatalysis, which is an emerging technology for water purification. In this thesis, low dimensional zinc oxide and copper oxides, which are promising photocatalytic materials, have been studied. READ MORE
