Several methods are employed to synthesize palladium shells, including:
Chemical Vapor Deposition (CVD): This method involves the deposition of palladium atoms onto the core material from a vapor phase precursor. Electroless Plating: This technique uses a chemical reduction process to deposit a palladium layer onto a substrate without the need for an external electric current. Colloidal Methods: These involve the reduction of palladium salts in a colloidal solution, which then deposit onto the core particles. Atomic Layer Deposition (ALD): This is a precise and controlled method for depositing atomic layers of palladium onto the core material.
