    • 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 ...

    • Reversed Hysteresis during CO Oxidation over Pd75Ag25(100) 

      Fernandes, Vasco Rafael P; Van der Bossche, Maxime; Knudsen, Jan; Farstad, Mari Helene; Gustafson, Johan; Venvik, Hilde Johnsen; Grönbeck, Henrik; Borg, Anne (Journal article; Peer reviewed, 2016)
      CO oxidation over Pd(100) and Pd75Ag25(100) has been investigated by a combination of near-ambient-pressure X-ray photoelectron spectroscopy, quadrupole mass spectrometry, density functional theory calculations, and ...
