      Metal–organic frameworks (MOFs) show great prospect as catalysts and catalyst support materials. Yet, studies that address their dynamic, kinetic, and mechanistic role in target reactions are scarce. In this study, an ...

    • Influence of Cu-speciation in mordenite on direct methane to methanol conversion: Multi-Technique characterization and comparison with NH3 selective catalytic reduction of NOx 

      Pappas, Dimitrios; Kvande, Karoline; Kalyva, Maria Evangelou; Dyballa, Michael Martin; Lomachenko, Kirill A.; Arstad, Bjørnar; Borfecchia, Elisa; Bordiga, Silvia; Olsbye, Unni; Beato, Pablo; Svelle, Stian (Peer reviewed; Journal article, 2020)
      The direct conversion of methane to methanol has the potential of substantially reducing methane emissions and flaring, as such a process might provide an alternative for remote natural gas locations. In this report, we ...

    • Methane to methanol: structure-activity relationships for Cu-CHA 

      Pappas, Dimitrios; Borfecchia, Elisa; Dyballa, Michael Martin; Pankin, Ilia A.; Lomachenko, Kirill A.; Martini, Andrea; Signorile, Matteo; Teketel, Shewangizaw; Arstad, Bjørnar; Berlier, Gloria; Lamberti, Carlo; Bordiga, Silvia; Olsbye, Unni; Lillerud, Karl Petter; Svelle, Stian; Beato, Pablo (Peer reviewed; Journal article, 2017)
      Cu-exchanged zeolites possess active sites that are able to cleave the C–H bond of methane at temperatures ≤200 °C, enabling its selective partial oxidation to methanol. Herein we explore this process over Cu-SSZ-13 ...

    • Shaping of metal-organic framework UiO-66 using alginates: Effect of operation variables 

      Lee, Daniel W; Didriksen, Terje; Olsbye, Unni; Blom, Richard; Grande, Carlos Adolfo (Peer reviewed; Journal article, 2020)
      Shaping of metal-organic frameworks into macro-structured particles for reactors and separation processes is a fundamental step in their way towards commercialization. Extrusion techniques which are used for shaping many ...
