  1. 1. Adsorption of Molecular Hydrogen on Cu, Pd and Ni Surfaces

    Författare :Krister Svensson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; electron energy loss spectroscopy; nickel; molecular chemisorption; hydrogen; palladium; physisorption; photodesorption; copper;

    Sammanfattning : This thesis is devoted to spectroscopic studies of molecular hydrogen adsorbed on metal surfaces. Hydrogen is the simplest molecule available and is a very valuable model adsorbate. From a spectroscopic point of view there are also three easily accessible molecular isotopes, H2, HD and D2, with widely different masses. LÄS MER

  4. 3. Thermal and Photon Driven Reactions of NO and H2O Adsorbed on Graphite

    Författare :Kristina Wettergren; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Water; Graphite; Silver Clusters; Sodium; Photodesorption; Nitric Oxide; Particle Plasmons;

    Sammanfattning : The topic of this thesis is the interaction of water (H2O) and nitric oxide (NO) with the graphite (C(0001)) surface. Specifically the effects of coadsorbing metals (Na, Ag) and subjecting the adsorption systems to thermal and photon activation were studied. LÄS MER

  5. 4. Thermal and Photon Stimulated Reactions on Metal Particles

    Författare :Kristina Wettergren; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Plasmons; Platinum Clusters; Platinum Nanoparticles; Hydrogen Oxidation; Sodium; Silver Nanoparticles; Nitric Oxide; Photodesorption; Sintering; Graphite; Water;

    Sammanfattning : The interaction between molecules and solid surfaces influence our daily lives in many ways. One important example is heterogeneous catalysis where surface reactions, for example, are used for production of chemicals and exhaust after-treatment. LÄS MER

  7. 5. Elementary Surface Processes on Graphite and Aluminium

    Författare :Lars Österlund; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Molecular processes on solid surfaces are of fundamental and technological importance. This work focuses on various reactive processes on a carbon (graphite(0001)) surface, and on the initial oxygen interaction with an aluminium (Al(111)) surface. LÄS MER
