Zeolite surface methoxy groups as key intermediates in the stepwise conversion of methane to methanol
This contribution clarifies the overoxidation-preventing key step in the methane-to-methanol (MTM) conversion over copper mordenite zeolites. We followed the methane-to-methanol conversion over copper mordenite zeolites by NMR spectroscopy supported by DRIFTS to show that surface methoxy groups (SMG...

Structural changes in the methanol-to-olefin (MTO) catalyst SAPO-34 after/during hydrothermal treatment
Structural changes in SAPO-34 due to hydrothermal treatment. A NMR, XRD, and DRIFTS study
When SAPO-34 is used as an industrial MTO catalyst, structural transformations leading to permanent deactivation are inevitable. The performance loss is linked principally to a redistribution of Si in the material, leading to the formation of Si-islands/aggregates with a concomitant loss of Brønsted...
Studies of SAPO-34 during and after hydrothermal treatment
in-situ DRIFTS and in-situ XRD studies of CaO and calcined dolomite during CO2 adsorption-desorption reactions
In-situ XRD studies of dolomite based CO2 sorbents
Calcined dolomite (a CaOMgO material derivative of the natural mineral dolomite) has the potential as a CO2 sorbent working at high temperatures (500-650 °C) in processes like post combustion carbonate-looping, or in sorbent enhanced reactions such as sorbent-enhanced water-gas shift (SEWGS) or sorb...
