Morphology-induced shape selectivity in zeolite catalysis

Morphology Induced Shape Selectivity in Zeolite Catalysis

Understanding zeolite catalysis: inverse shape selectivity revised.

Anyone who has experience in moving house [the Angewandte team has just done this!] knows that those boxes filled with small books are the heaviest, because these small objects pack so easily. The same entropy effect explains the catalytic selectivity towards the formation of branched hydrocarbons in zeolites. The pink tubes represent the zeolite pores at high loading in which effective size di...

Zeolite Catalysis

The Special Issue “Zeolite Catalysis” published in the online journal Catalysts was recently successfully completed. A good number of peer-reviewed publications were published reflecting the broadness of the zeolite syntheses, characterizations and various application fields. This issue brought together recent research of well-known research teams from all over the world. The term “zeolite” is ...

Solvent Polarity-Induced Pore Selectivity in H-ZSM-5 Catalysis

Molecular-sized micropores of ZSM-5 zeolite catalysts provide spatial restrictions around catalytic sites that allow for shape-selective catalysis. However, the fact that ZSM-5 has two main pore systems with different geometries is relatively unexploited as a potential source of additional shape selectivity. Here, we use confocal laser-scanning microscopy to show that by changing the polarity o...
