    Abstract : This thesis discusses the use of biomass as a potentially green feedstock for the chemical industry in the urgent shift away from fossil resources. I elaborate on reasons why we cannot afford to burn virgin biomass for energy production, among them a variety of ecosystem services that forests and other lands provide. READ MORE

  5. 18. Porous Cerium Dioxide for Catalytic Applications

    Author : Mats Lundberg; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; materialteknik; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Materiallära; Material technology; catalysis; transmission electron microscopy; macroporous; mesoporous; cerium dioxide; zirconium dioxide;

    Abstract : Mesoporous cerium dioxide with high crystallinity has been synthesized and studied by TEM, SEM, nitrogen adsorption, PXRD, AFM, and SAXS. The catalytic properties of the materials have been investigated The results of the catalysis experiments were correlated with high resolution TEM investigations of the corresponding material, and it was found that the exposed crystallographic facets play an important role in the conversion of carbon monoxide to carbon dioxide.
