Cover Feature: Elucidating the Sectioning Fragmentation Mechanism in Silica‐Supported Olefin Polymerization Catalysts with Laboratory‐Based X‐Ray and Electron Microscopy (ChemCatChem 21/2022)

The Cover Feature shows an artistic interpretation of a supported polymerization catalyst particle that is fragmenting during ethylene polymerization. In their Research Article, F. Meirer, B. M. Weckhuysen and co-workers used high resolution X-ray electron microscopy to elucidate the origins sectioning fragmentation mechanism in two different silica-supported olefin catalysts at single level. occurrence was shown be favoured by low degree macroporosity silica granulates constituting support, accessibility interior reaction onset, as well fast kinetics.
