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 ... -
