  • Ethene Alkylation: Kinetics and Mechanism 
    Ahoba-Sam, Christian (Master thesis / Masteroppgave, 2014)
  • 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 ...
  • Low temperature methanol synthesis catalyzed by copper nanoparticles 
    Ahoba-Sam, Christian; Olsbye, Unni; Jens, Klaus-Joachim (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    A one pot catalytic system which involves Cu and an alkoxide co-catalyst has been used for methanol (MeOH) synthesis at low temperature. Up to about 92% syngas conversion per pass and more than 90% selectivity to MeOH (the ...
  • On the conversion of CO2 to value added products over composite PdZn and H-ZSM-5 catalysts: excess Zn over Pd, a compromise or a penalty? 
    Ahoba-Sam, Christian; Borfecchia, Elisa; Lazzarini, Andrea; Bugaev, Aram L.; Isah, Abdulrahman Adamu; Taoufik, Mostafa; Bordiga, Silvia; Olsbye, Unni (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    A challenge in converting CO2 into hydrocarbons (HC) via methanol (MeOH) is the gap between the optimal temperature for each step (i.e. ≤250 °C for MeOH and ≥350 °C for HC). The focus of this study is to elucidate the cause ...
  • Tailoring Cu nanoparticle catalyst for methanol synthesis using the spinning disk reactor 
    Ahoba-Sam, Christian; Boodhoo, Kamelia V.K.; Olsbye, Unni; Jens, Klaus-Joachim (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Cu nanoparticles are known to be very active for methanol (MeOH) synthesis at relatively low temperatures, such that smaller particle sizes yield better MeOH productivity. We aimed to control Cu nanoparticle (NP) size and ...
  • The Role of Solvent Polarity on Low-Temperature Methanol Synthesis Catalyzed by Cu Nanoparticles 
    Ahoba-Sam, Christian; Olsbye, Unni; Jens, Klaus-Joachim (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Methanol syntheses at low temperature in a liquid medium present an opportunity for full syngas conversion per pass. The aim of this work was to study the role of solvents polarity on low-temperature methanol synthesis ...
