Selectivity driving parameters in redox reactions catalyzed by Lewis acid zeolites.

Project supervisor Ing. Jan Přech, Ph.D. 

Zeolites are robust and environmentally friendly heterogeneous catalysts. They contain framework metal ions, which act as Bronsted or Lewis acid sites. In particular, …

Hydrogenation catalysts made by reductive demetalation of zeolites

Metal nanoparticles on a support are typical hydrogenation catalysts. Zeolite-like(molecular sieve) supports introduce shape selectivity, stabilize metal nanoparticles and provide additional catalytic function. Bimetallic catalysts may be more advantageous than …

Metal nanoparticles supported at zeolitic materials

We explore the interactions of metal nanoparticles with zeolitic support. These insights allow us to prepare well-distributed, stable subnanometric metal particles immobilized at zeolites, with special interests in novel, layered-based …

Engineering key features of zeolite active sites

Around 200 of 850 industrial catalytic processes utilize zeolites. Although traditional synthetic approaches are excellent tools for tuning the chemical composition of zeolite catalysts, they are still unable to control …
