  2. 1. MECHANISMS OF ENHANCED ACTIVITY OF MODEL TiO2/CARBON and TiO2/METAL NANOCOMPOSITE PHOTOCATALYSTS

    Author : Raja Sellappan; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Photocatalysis; graphite; solar energy conversion; graphene; localized surface plasmon resonance; photocatalytic mechanisms; nanocomposites; TiO2; carbon;

    Abstract : TiO2 is the most widely used photocatalyst for energy and environmental applications because of its outstanding physical and chemical properties. However, the quantum efficiency of TiO2 is greatly diminished by fast electron-hole pairs recombination and light absorption only in the UV region. READ MORE

  4. 2. Mimicking Photosystem II with Manganese Model Complexes to Approach Artificial Photosynthesis

    Author : Joakim Högblom; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Metabolism; Hydrogen; EPR; Cobalt; Biokemi; metabolism; Biochemistry;

    Abstract : The work in thesis aims for artificial photosyntesis, which could and will mimic natural photosynthesis, the process that uses light to create energy rich compounds from H2O and CO2. Water is oxidized in Photosystem II (PSII) by the Water Oxidizing Complex (WOC), which is a catalytic site on the lumenal side of the thylakoid membrane. READ MORE
