Oxygen species involved in selective and unselective pathways were investigated using O2 and N2O as the oxidants. Spatially resolved and steady-state kinetic analyses combined with oxygen isotopic exchange tests were used to identify the activity-defining descriptor over M2WO4/SiO2 (M=Na, K, Rb, or Cs). The effects of alkali metal for both bi- and trimetallic compositions on activity and selectivity were established UR - http://purl.uni-rostock.de/rosdok/id00004386 UR - https://nbn-resolving.org/urn:nbn:de:gbv:28-rosdok_id00004386-5 UR - https://d-nb.info/1297583310/34 UR - https://doi.org/10.18453/rosdok_id00004386 DO - 10.18453/rosdok_id00004386 LA - English N1 - vorgelegt von Anna Zanina ID - 1853798460 ER -
