• Co(11-20) and Pd3Au(100) single crystals as catalyst model systems 

      Strømsheim, Marie Døvre (Doctoral theses at NTNU;2017:372, Doctoral thesis, 2017)
      The work in this thesis was carried out with the overall goal to investigate surface dynamics of model catalyst surfaces. Single crystals were utilized as model systems, namely Co(11-20) and Pd3Au(100). The Co(11-20) ...
    • Effects of K adsorption on the CO-induced restructuring of Co(11-20) 

      Strømsheim, Marie Døvre; Svenum, Ingeborg-Helene; Farstad, Mari Helene; Li, Zheshen; Gavrilovic, Ljubisa; Guo, Xiaoyang; Lervold, Stine; Borg, Anne; Venvik, Hilde Johnsen (Journal article; Peer reviewed, 2017)
      The location of potassium (K) on Cobalt (Co) and its effect on adsorption and adsorption-induced surface restructuring is important for understanding the deactivation of Co Fischer-Tropsch catalysts and the nature of the ...
    • Interaction of hydrogen with flat (0001) and corrugated (11–20) and (10–12) cobalt surfaces: Insights from experiment and theory 

      Weststrate, Kees-Jan; Mahmoodinia, Mehdi; Farstad, Mari Helene; Svenum, Ingeborg-Helene; Strømsheim, Marie Døvre; Niemantsverdriet, Hans; Venvik, Hilde Johnsen (Journal article; Peer reviewed, 2019)
      Cobalt catalysts are used on a commercial scale to produce synthetic fuels via the Fischer-Tropsch synthesis process. As adsorbed hydrogen atoms are involved in many of the elementary reaction steps that occur on the ...
    • Investigations of Pd3Au(100) as a catalytic model system 

      Hådem, Gaute Osaland (Master thesis, 2018)
      Catalysts are defined as materials that lowers the activation energy of a reaction, without being consumed. In heterogeneous catalysis they are commonly transitions metals which have been refined to small particles using ...
    • Investigations of PdAu membranes and model systems for production of pure hydrogen 

      Sørvik, Linn Cecilie (Master thesis, 2015)
      Hydrogen production from carbon-containing energy sources can capture the CO2 on site, and therefore reduce the contribution to global warming. The only emission when energy is produced through a fuel cell is H2O. Another ...
    • Near Ambient Pressure XPS Investigation of CO Oxidation Over Pd3Au(100) 

      Strømsheim, Marie Døvre; Knudsen, Jan; Farstad, Mari Helene; Sørvik, Linn Cecilie; Guo, Xiaoyang; Venvik, Hilde Johnsen; Borg, Anne (Journal article; Peer reviewed, 2017)
      The CO oxidation behavior under excess oxygen and near stoichiometric conditions over the surface of Pd3Au(100) has been studied by combining near-ambient pressure X-ray photoelectron spectroscopy and quadrupole mass ...
