  • How Surface Species Drive Product Distribution during Ammonia Oxidation: An STM and Operando APXPS Study 
    Ivashenko, Oleksii; Johansson, Niclas; Pettersen, Christine; Jensen, Martin; Zheng, Jian; Schnadt, Joachim; Sjåstad, Anja Olafsen (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    The oxidation of ammonia is a key reaction for the production of artificial fertilizers and for environmental protection. Depending on the area of application, the catalytic reaction needs to be tuned toward the production ...
  • Insights into Crystal Structure and Diffusion of Biphasic Na2Zn2TeO6 
    Li, Xinyu; Bianchini, Federico; Wind, Julia; Pettersen, Christine; Vajeeston, Ponniah; Wragg, David; Fjellvåg, Helmer (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    The layered oxide Na2Zn2TeO6 is a fast Na+ ion conductor and a suitable candidate for application as a solid-state electrolyte. We present a detailed study on how synthesis temperature and Na-content affect the crystal ...
  • Near-Surface Alloys of PtRh on Rh(111) and Pt(111) Characterized by STM 
    Pettersen, Christine; Sjåstad, Anja Olafsen; Ivashenko, Oleksii (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    The use of Pt–Rh catalysts is central in a number of industrial processes, and to explain their performance it is essential to have a solid understanding of their nanoscopic surface structure. Here we use scanning tunneling ...
  • Preparation, Characterization and Oxidation of Nanostructured Pt-Rh Surfaces 
    Pettersen, Christine (Master thesis / Masteroppgave, 2020)
