  1. 1. Palladium-based Nanoplasmonics for Ultrafast and Deactivation-Resistant Hydrogen Detection

    Författare :Iwan Darmadi; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; plasmonic sensing; palladium hydride; palladium; polymer; localized surface plasmon resonance; Pd; nanoparticle; surfactant; hydrogen; palladium alloy; hydrogen sensor;

    Sammanfattning : In the hydrogen economy scenario, hHydrogen gas is ispotential to be the main energy carrier in the hydrogen economy scenario in the upcoming future. It receives much attention since the reaction with oxygen generates electricity and produces only clean waterhydrogen is attractive as energy carrier since the energy produced by its reaction with oxygen only producesleaves water as by-product.

  2. 2. Studies of Molecular Interactions with Single Nanoparticles: Combining in Situ Plasmonic Nanospectroscopy with Transmission Electron Microscopy

    Författare :Sara Nilsson; Chalmers University of Technology; []
    Nyckelord :palladium hydride; oxidation; grain boundary; transmission electron microscopy; dark-field scattering spectroscopy; heterogeneous catalysis; single nanoparticle; plasmonic nanospectroscopy; localized surface plasmon resonance sensing;

    Sammanfattning : The cyclic methanol and hydrogen economies are two viable options in the strive for clean energy production. Industrial methanol synthesis is conducted over copper (Cu)-based catalysts. However, Cu is prone to oxidation, which leads to Cu catalyst deactivation. LÄS MER

  3. 3. Alloy Plasmonics - Fundamentals and Applications

    Författare :Christopher Tiburski; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; palladium-hydride; heterogeneous catalysis; nanoalloys; sensing; photothermal; gold-palladium; plasmonics; dielectric function; nanothermometry; CO oxidation;

    Sammanfattning : Alloys have for a long time been important in the development of our society; from the Bronze Age, where man learned how to alloy copper with tin, to today, where many products are made of steel and aluminum alloys. Similarly, but maybe not as generally well known, alloys have lately been proposed as a new paradigm in nanophotonics, to tailor optical properties of nanomaterials that find applications within telecommunication, sensing, or biotechnology.

  4. 4. Activation of CO2 by Palladium Complexes Bearing Tridentate PCP Ligands

    Författare :Roger Johansson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Metallorganisk kemi; Organometallic chemistry; Kinetics; Insertion reactions; PCP ligands; CO2 activation; Palladium II complexes;

    Sammanfattning : The present thesis deals with the activation of CO2 by insertion reactions into palladium-carbon bonds. This has been realised for the complexes {2,6-bis[(di-t-butylphosphino)methyl]benzene}palladium(II)methyl [(PCP)PdMe] and (PCP)PdCH2CHCH2. These complexes have also been used in the catalytic carboxylation of ZnMe2 and Bu3SnCH2CHCH2. LÄS MER
