  1. 1. Catalytic reactions with palladium supported on mesocellular foam : Applications in hydrogenation, isomerization, and C-C bond forming reactions

    Författare :Anuja Nagendiran; Jan-Erling Bäckvall; Shu Kobayashi; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mesocellular foam; Heterogeneous palladium catalysis; nanopalladium; organisk kemi; Organic Chemistry;

    Sammanfattning : The major part of this thesis concerns the development of catalytic methodologies based on palladium nanoparticles immobilized on aminopropyl-functionalized siliceous mesocellular foam (Pd0-AmP-MCF). The catalytic activity of the precursor to the nanocatalyst, PdII-AmP-MCF is also covered by this work. LÄS MER

  3. 2. New Tools for Green Catalysis : Studies on a Biomimetic Hybrid Catalyst and a Novel Nanopalladium Catalyst

    Författare :Eric Johnston; Jan Erling Bäckvall; Roger Sheldon; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; organisk kemi; Organic Chemistry;

    Sammanfattning : The first part of this thesis describes an improved synthetic route to hybrid (hydroquinone-Schiff base)cobalt catalysts. Preparation of the 5-(2,5-hydroxyphenyl)salicylaldehyde building block was improved by altering the protective groups of the hydroquinone (HQ) starting material. LÄS MER

  4. 3. Development and Applications of Surface-Confined Transition Metal Complexes : Heterogeneous Catalysis and Anisotropic Particle Surfaces

    Författare :Kristofer Eriksson; Jan-Erling Bäckvall; Graham Hutchings; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; heterogeneous catalysis; anisotropic particles; protein gradients; nanoparticles; organisk kemi; Organic Chemistry;

    Sammanfattning : The main focus of this thesis has been directed towards developing novel surface-confined transition metal complexes for applications in heterogeneous catalysis and for the preparation of anisotropic particle surfaces. The first part describes the heterogenization of a homogeneous transition metal-based catalyst tetraphenyl cobalt porphyrin (CoTPP) on silicon wafers and on silica particles. LÄS MER
