  2. 1. Photocatalysis for Indoor Air Cleaning : In situ FTIR and DFT Study of Acetaldehyde Photo-Oxidation on TiO2 and Sulfate-Modified TiO2

    Author : Bozhidar Stefanov; Lars Österlund; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TiO2; acetaldehyde; crotonaldehyde; dimer; adsorption; DFT; FTIR; photocatalysis; micro-kinetic modeling; acid–base properties; surface functionalization; Solid State Physics; Fasta tillståndets fysik; Materialvetenskap; Materials Science;

    Abstract : Acetaldehyde is among the group of VOC’s causing the so-called "sick building" syndrome. WHO has estimated that this problem, related to the indoor air-quality, affects one third of all buildings worldwide. TiO2 is an attractive material for the photocatalytic removal of VOC’s in the indoor environment. READ MORE

    Abstract : Poor indoor air quality is a source of adverse health effects. TiO2 coatings deposited on well-illuminated surfaces, such as window panes, can be used to fully mineralize indoor air pollutants by photocatalysis. READ MORE

  5. 3. First Principles Studies on Chemical and Electronic Structures of Adsorbates

    Author : Wenhua Zhang; Yi Luo; Gianfranco Pacchioni; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Solid state chemistry; Fasta tillståndets kemi; Computational physics; Beräkningsfysik; Surfaces and interfaces; Ytor och mellanytor;

    Abstract : In this thesis, we focus on theoretical study of adsorbates on metal and oxide surfaces that are important for surface chemistry and catalysis. Based on first principles calculations, the adsorption ofCO, NO, NO2, C4H6S2, C22H27SH and other molecules or radicals on nobel metal surfaces (gold and silver) are investigated. READ MORE
