  1. 1. Colloidal zeolites : from nucleation to zoned films by seeded growth

    Författare :Qinghua Li; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

    Sammanfattning : The work presented in this thesis concerns the investigation of nucleation kinetics for colloidal zeolites, especially the determination of the nucleation period during crystallization. It also concerns the use of colloidal TPA-silicalite-1 for the preparation of zoned MFI films. LÄS MER

  3. 2. Synthesis and Applications of Colloidal Zeolites and Transition Metal Functionalized Ordered Mesoporous Carbons

    Författare :Walter Rosas Arbelaez; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; colloidal zeolites; CO2 capture; hierarchical zeolites; growth mechanism; Fe-N-doped ordered mesoporous carbon; fuel cell.;

    Sammanfattning : Porous materials have attracted a great deal of attention of the materials science community, owing to their physical and chemical properties including high surface areas, narrow pore size distribution, tunable pore diameters and variety of chemical compositions. These properties make them suitable for various applications such as adsorption, sensing, catalysis, energy, carbon capture and drug delivery. LÄS MER

  4. 3. Synthesis and applications of low silica zeolites from Bolivian clay and diatomaceous earth

    Författare :Javier Gustavo Garcia Mendoza; Johanne Mouzon; Niklas Hedin; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Zeolites; Synthesis; clay; diatomite; adsorption; ion exchange; Chemical Technology; Kemisk teknologi;

    Sammanfattning : The aim of the present work was to develop synthesis routes to produce synthetic zeolites with industrial attractiveness from non-expensive Bolivian raw materials, such as clays and diatomite. In particular, the work was focused on the synthesis of low-silica zeolites with the LTA and FAU structures. LÄS MER
