Palladium (Pd) is a versatile catalyst in various chemical reactions, including hydrogenation, carbon-carbon coupling, and oxidation reactions. Using a palladium shell can offer several advantages:
Cost Efficiency: By limiting the use of palladium to a thin shell, the overall amount of this expensive metal is reduced, making the catalyst more cost-effective. Enhanced Activity: The catalytic activity can be significantly boosted due to the high surface area of the palladium shell. Stability: The core material can provide structural stability, preventing the palladium shell from agglomerating or sintering during reactions. Selectivity: The core-shell structure can be tailored to promote specific reaction pathways, thereby enhancing selectivity.
