  1. 1. Application of Fourier Transforms to time-resolved ambient pressure spectroscopy operando studies of CO oxidation over Pt(111)

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Författare :Grigore-Leon Ratiu; [2024]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The study of heterogeneous catalysis has important implications in increasing the efficiency of industrial processes and in reducing the emissions of greenhouse gases from sources such as automobiles. A reaction with high industrial relevance is the oxidation of CO on noble metal catalysts. LÄS MER

  3. 2. Development of synthetic methodology for non-symmetric fullerene dimers

    Kandidat-uppsats, Uppsala universitet/Institutionen för kemi - BMC

    Författare :Fredrik Barnå; [2019]
    Nyckelord :fullerene; dumbbell; Prato; rhodium catalysis; fullerene dimer; HPLC; amino acid; cyclo addition; alkylation; solubility;

    Sammanfattning : This bachelor thesis covers the initial development of a synthesis of fullerene dimers using two different types of linking reactions. Different setups for [3+2] cycloadditions to fullerenes (Prato reaction) were tested, and for that purpose, an N-alkylated amino acid was synthesised. LÄS MER

  4. 3. Preparation, characterization and testing of model catalysts for CO oxidation and CO2 hydrogenation

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Författare :Stefano Albertin; [2017]
    Nyckelord :Surface science; Rhodium; Nanoparticles; Catalysis; CO2; Physics and Astronomy;

    Sammanfattning : A joint research between Lund University and Chalmers Competence Centre for Catalysis have shown promising results for a Rh-based catalyst for CO2 hydrogenation catalytic applications. The original catalyst consisted of a dispersion of nanoparticles onto a porous 3D oxide network. LÄS MER

  5. 4. CO induced faceting of Rh(553)

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Författare :Ka Sin Lai; [2015]
    Nyckelord :Science General;

    Sammanfattning : We have investigated the CO induced faceting of a Rh(553) surface using Scanning Tunneling Microscope (STM), Low Energy Electron Diffraction (LEED) and Auger Electron Spectroscopy (AES). The sample was exposed to a CO pressure of 1x10^-3 mbar, at different sample temperatures. LÄS MER
