Investigator: Bulánek Roman
Description:
Encapsulation of metal nanoparticles in zeolites plays an important role in improving the catalytic performance of solid catalysts in a number of important reactions. In this project, attention is paid to copper nanoparticles, which have significant potential in the catalytic conversion of CO2 to value-added chemicals and the dehydrogenation of ethanol to acetaldehyde and hydrogen. Both reactions are industrially important and interesting reactions meeting the criteria of green and sustainable chemistry. The main goals include shedding light on the influence of the geometry of the confined space of zeolite micropores on the size and morphology of nanoparticles, as well as the influence of the interactions of nanoparticles with the zeolite wall, modulated by changing the composition, framework charge and the presence of a charge compensating cation, on the electronic state of Cu nanoparticles and consequently on the catalytic activity. A fundamental understanding of these effects is crucial for further improving the catalytic performance of Metal@zeolite catalysts.
