  1. 6. 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

  3. 7. Optimizing a Single Atom Catalyst for theOxygen Evolution Reaction using DensityFunctional Theory

    Uppsats för yrkesexamina på avancerad nivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Vivien Hjelm; [2019]
    Nyckelord :Single atom catalyst; oxygen evolution reaction; density functional theory; heterogeneous catalyst; transition metals;

    Sammanfattning : The growing interest of renewable fuel and energy sources has steadily increased over time due to climate changes. Research is being made around the world to find solutions for the different problems; one possible solution is to produce hydrogen gas to help phase out the usage of fossil fuels. LÄS MER

  5. 9. 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

  7. 10. 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
