What are Zeolite-Based Nanocatalysts?
Zeolite-based nanocatalysts are specialized materials that combine the unique properties of zeolites and nanotechnology to enhance catalytic processes. Zeolites are microporous, aluminosilicate minerals with a well-defined crystalline structure, which makes them effective catalysts. When these zeolites are engineered at the nanoscale, their surface area, reactivity, and selectivity can be significantly improved.
How do Zeolite-Based Nanocatalysts Work?
Zeolite-based nanocatalysts operate by providing a large surface area for chemical reactions to occur. The nanoporous structure of zeolites allows for the selective adsorption of reactants, while the active sites within the framework facilitate the catalytic process. The nanoscale size of these catalysts ensures that a higher proportion of atoms are exposed to the reactants, thus increasing the overall efficiency of the reaction.
