Research topics

Hydrogenation catalysts made by reductive demetalation of zeolites

16 Jan 2023

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 ...

Metal nanoparticles supported at zeolitic materials

16 Jan 2023

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

16 Jan 2023

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 ...

Novel materials for photo(electro)catalytic conversion of CO2

16 Jan 2023

Development of novel photo(electro)catalysts for conversion of green-house gas CO2 is crucial to reach sustainable approach in carbon economy. Our work is focused on synthesis of advanced hybrid ...

Open positions

PhD fellow in "Multifunctional zeolite materials for processing of platform chemicals and their derivatives"

Project summary:

Due to molecular sieving effect, high adsorption capacity and adjustable chemical composition zeolites are efficient catalysts for a number of processes. However, there is still a lack of synthesis tools for generation of active centers of particular characteristics at particular location in the zeolite frameworks. In addition, there ... more

PhD fellow in "Selectivity driving parameters in redox reactions catalyzed by Lewis acid zeolites"

Project summary:

Zeolites are robust and environmentally friendly heterogeneous catalysts. They contain framework metal ions, which act as Bronsted or Lewis acid sites. In particular, the Lewis acid sites (generated, e.g., by incorporated Ti, Sn, Zr, and Hf ions) catalyze selective redox reactions such as oxidation with peroxides or hydrogen ... more

PhD fellow in "Stabilization of metal clusters on the zeolite supports and their assessment by in-situ electron microscopy methods"

Project summary:

Metal nanoparticles immobilized at zeolite supports are important class of heterogenous catalysts for hydrogenation and dehydrogenation, reforming, and water-gas shift reactions. Zeolites, porous elementosilicates, are used to encapsulate metal nanoparticles to improve their stability. Currently, in-situ encapsulation and post-synthesis functionalization are two main synthesis strategies for metal incorporation ... more

PhD fellow in "Synthesis of novel zeolites and their structure determination by advanced electron diffraction"

Zeolites are porous elementosilicates with vast applications in the fields of catalysis, sorption, and ion-exchange. Their advantage lies in properties, such as high adsorption capacity, defined microporosity (resulting in molecular sieving effect), adjustable chemical composition, and possibility for post-synthesis modifications. Conventional synthesis of zeolites uses solvothermal methods that are limited ... more

PhD fellow in "Understanding active sites of zeolite catalysts"

Project summary:

Heterogeneous single-site catalysts are the latest generation materials enabling to maximize the profit and minimize the waste-related issues during production of important chemicals. Although zeolites have been the key industrial catalysts for several decades, development of their single-site representatives as well as analytical techniques for detailed characterization of ... more
