  • Correlation between surface chemistry and morphology of PtCu and Pt nanoparticles during oxidation-reduction cycle 
    Kalyva, Maria Evangelou; Sunding, Martin Fleissner; Gunnæs, Anette Eleonora; Diplas, Spyridon; Redekop, Evgeniy (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Process conditions during catalytic reactions induce significant changes in surface chemistry and structure of bi- (mono) metallic nanoparticles leading to their deactivation, and this can ultimately affect the reactions ...
  • Influence of Defects and H2O on the Hydrogenation of CO2 to Methanol over Pt Nanoparticles in UiO-67 Metal-Organic Framework 
    Gutterød, Emil Sebastian; Pulumati, S.H.; Kaur, Gurpreet; Lazzarini, Andrea; Solemsli, B. G.; Gunnæs, Anette Eleonora; Ahoba-Sam, Christian; Kalyva, Maria Evangelou; Sannes, Johnny Andreas; Svelle, Stian; Skúlason, Egill; Nova, Ainara; Olsbye, Unni (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    In catalysts for CO2 hydrogenation, the interface between metal nanoparticles (NPs) and the support material is of high importance for the activity and reaction selectivity. In Pt NP-containing UiO Zr-metal–organic frameworks ...
  • One-pot synthesis of cobalt-rhenium nanoparticles taking the unusual beta-Mn type structure 
    Zacharaki, Eirini; Bremmer, Marien G.; Vajeeston, Ponniah; Kalyva, Maria Evangelou; Fjellvåg, Helmer; Kooyman, Patricia J.; Sjåstad, Anja Olafsen (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Using a facile one-pot colloidal method, it is now possible to obtain monodisperse Co1−xRex nanoparticles (NPs), with excellent control of Re stoichiometry for x < 0.15. Re-incorporation in terms of a solid solution ...
