Heterogene Katalyse. In ihrer Zuschrift (e202207777) nutzen Patrick Hemberger et al. PEPICO-Spektroskopie zur Identifizierung von Keten- und Methylketen-Intermediaten in der Methylacetat-Umwandlung über HZSM-5-Zeolith.

In order to reduce the harmful constituents in cigarette smoke, two hierarchical composites were synthesized. Based on, zeolites HZSM-5 or NaY fragments were introduced into the synthetic system of mesoporous silica SBA-15 or MCM-41 and assembled with the mesoporous materials. These porous composites combine the advantages of micro- and mesoporous materials, and exhibit higher effects than acti...
