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.
Keywords:
copper; nanoparticles; encapsulation; zeolite; CO2 hydrogenation; ethanol dehydrogenation
The project aims to deepen the understanding of the effect of encapsulation on the properties of
metal nanoparticles located inside zeolite pores and cavities, especially the effect of confined
space geometry on the catalytic activity of copper nanoparticles in environmentally important
processes.
