Core Shell Nanostructures - Catalysis

What are Core Shell Nanostructures?

Core shell nanostructures are a type of nanomaterial with a distinct core and shell composition. The core is typically composed of one material, while the shell is made of another. This unique architecture allows for the combination of different properties from each component, often leading to enhanced performance in various applications, including catalysis.

Why are Core Shell Nanostructures Important in Catalysis?

Core shell nanostructures offer several advantages in catalysis, such as increased stability, improved activity, and enhanced selectivity. The core can provide structural support and additional functionalities, while the shell can be tailored to optimize the interaction with reactants and intermediates.

How are Core Shell Nanostructures Synthesized?

The synthesis of core shell nanostructures typically involves a combination of chemical and physical methods. Common techniques include sol-gel processes, co-precipitation, and thermal decomposition. These methods allow precise control over the size, composition, and morphology of the core and shell.
